The title compound (I) was prepared as an unexpected product in our work by the following procedure: A solution of Schiff base ligand, 1,5-Bis[(1E)-4-methoxybenzylidene]thiocarbonohydrazide, (0.342 g, 1 m mol) and dibutyltin dichloride (0.304 g, 1 m mol) in acetonitrile (20 ml) was heated for 8 h under reflux. The reaction mixture was then cooled and the pale yellow precipitate that had formed was filtered off. Recrystallization of the crude product from ethanol-DMF solution resulted in single crystals of (I) suitable for X-ray diffraction analysis after several days.
Slightly disorder in the ethanol was identified from the difference map. Disordered atoms were refined by applying restraints to the bond lengths [1.540 (2)Å for C35—C36 and 1.340 (2)Å for C35—O4]. All the H atoms were positioned in idealized locations and refined as riding on their carrier atoms, with O—H distances of 0.82 (hydroxyl), C—H distances of 0.93 (aryl), 0.97 (methylene) and 0.96Å (methyl) with Uiso(H) = 1.5Ueq(C) for hydroxyl and methyl, Uiso(H) = 1.2Ueq(C) for the other atoms.
Organotin complexes have attracted attention in supermolecular chemistry in recent years (Ma et al., 2005; Barbieri et al., 2001), whereas thiosemicarbazones and their complexes have a wide range of applications in biology (Casas et al., 2000). In the context of our continuous interest for the structural and biological properties of organotin compounds (Fang et al., 2001; 2006a), we report here the crystal structure of the title complex, (I). To the best of our knowledge, this is the first example of organotin complex containing C2N2S2Sn2 planar dicyclo fragment.
The structure of (I) is an unexpected product in our work. It crystallizes in space group P-1, with one half-molecule of an organotin complex [2,2,6,6-Tetra-n-butyl-2,6-dichloro-4,8-di[(1E)-4-methoxybenzylidene]ηydrazino-1,5-diaza-2,6-distanna-3,7-dithiabicyclo[3.3.0]octane], one substituted thiocarbonohydrazide ligand [1,5-Bis[(1E)-4-methoxybenzylidene]thiocarbonohydrazide] and one ethanol molecule in the asymmetric unit (Fig. 1). Part of the thiocarbonohydrazide ligand molecules were cracked to form a novel substituted C2N2S2Sn2 planar dicyclo organotin complex. The five-membered ring Sn1—S1—C1—N1A—N1 is coplanar with a mean deviation of 0.024 (3) Å. The inversion center is situated at the midpoint of N1—N1A bond, and it is by this bond that the two five-membered rings are fused together. Both of the SnIV atoms are penta-coordinated with distorted trigonal-bipyramidal geometry. C10, C14 (from butyl groups) and S1 atom occupy the equatorial plane, these equatorial atoms and relative Sn atom are nearly coplanar, the mean deviation from the plane is 0.031 (4) Å. Cl1 and N1 atoms occupy the axial positions with the N1—Sn1—Cl1 bond angle 160.11 (6)°. All the C═ N bonds exist in E-configuration, and all the bond lengths in (I) are within the expected range and agree well with literature values (Altmann et al., 1998; Fang et al., 2006).
In the crystal lattice, every two molecules of the ligand are linked by the weak hydrogen bonds N6—H6···S2i to form dimers, with the attached two ethanol molecules by the strong N5—H5···O4ii and weak C25—H25···O4ii hydrogen bonds. The molecules of organotin are linked by S···S interactions (Wang et al., 2004). and N—H···Cliii, C—H···Cliii weak hydrogen bonds involving all potential S and Cl atom donors, generating one-dimensional infinite chains parallel to the a axis, as shown in Fig. 2. The 4-methoxyphenyl rings protrude on both sides of these chains and have no special intercalations [symmetry codes: (i) -x + 1, -y + 1, -z + 1; (ii) -x + 1, -y + 2, -z + 1; (iii) -x + 1, -y + 2, -z].

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

Organotin complexes have attracted attention in supermolecular chemistry in recent years (Ma et al., 2005; Barbieri et al., 2001), whereas thiosemicarbazones and their complexes have a wide range of applications in biology (Casas et al., 2000). In the context of our continuous interest for the structural and biological properties of organotin compounds (Fang et al., 2001; 2006a), we report here the crystal structure of the title complex, (I). To the best of our knowledge, this is the first example of organotin complex containing C2N2S2Sn2 planar dicyclo fragment.
The structure of (I) is an unexpected product in our work. It crystallizes in space group P-1, with one half-molecule of an organotin complex [2,2,6,6-Tetra-n-butyl-2,6-dichloro-4,8-di[(1E)-4-methoxybenzylidene]ηydrazino-1,5-diaza-2,6-distanna-3,7-dithiabicyclo[3.3.0]octane], one substituted thiocarbonohydrazide ligand [1,5-Bis[(1E)-4-methoxybenzylidene]thiocarbonohydrazide] and one ethanol molecule in the asymmetric unit (Fig. 1). Part of the thiocarbonohydrazide ligand molecules were cracked to form a novel substituted C2N2S2Sn2 planar dicyclo organotin complex. The five-membered ring Sn1—S1—C1—N1A—N1 is coplanar with a mean deviation of 0.024 (3) Å. The inversion center is situated at the midpoint of N1—N1A bond, and it is by this bond that the two five-membered rings are fused together. Both of the SnIV atoms are penta-coordinated with distorted trigonal-bipyramidal geometry. C10, C14 (from butyl groups) and S1 atom occupy the equatorial plane, these equatorial atoms and relative Sn atom are nearly coplanar, the mean deviation from the plane is 0.031 (4) Å. Cl1 and N1 atoms occupy the axial positions with the N1—Sn1—Cl1 bond angle 160.11 (6)°. All the C═ N bonds exist in E-configuration, and all the bond lengths in (I) are within the expected range and agree well with literature values (Altmann et al., 1998; Fang et al., 2006).
In the crystal lattice, every two molecules of the ligand are linked by the weak hydrogen bonds N6—H6···S2i to form dimers, with the attached two ethanol molecules by the strong N5—H5···O4ii and weak C25—H25···O4ii hydrogen bonds. The molecules of organotin are linked by S···S interactions (Wang et al., 2004). and N—H···Cliii, C—H···Cliii weak hydrogen bonds involving all potential S and Cl atom donors, generating one-dimensional infinite chains parallel to the a axis, as shown in Fig. 2. The 4-methoxyphenyl rings protrude on both sides of these chains and have no special intercalations [symmetry codes: (i) -x + 1, -y + 1, -z + 1; (ii) -x + 1, -y + 2, -z + 1; (iii) -x + 1, -y + 2, -z].
