To an aqueous solution of Bi(NO3)35H2O (2.0 mmol) and mannite (2.0 mmol) was added another aqueous solution of sodium pyrrolidine-1-dithiocarboxylate (4.0 mmol) and 2,2'-bipyridine (2.0 mmol). The resulted solution was stirred for 2 h at 298 K, and then yellow solid was obtained by filtration. The solid was recrystallized from ethanol and yellow crystals of (I) were formed.
All H atoms were positioned geometrically and treated as riding on their parent atoms [C—H = 0.97 Å with Uiso(H) = 1.2Ueq for CH2, and C—H =0.93 Å with Uiso(H) = 1.2Ueq for aromatic H atoms].
Dithiocarbamates have been known as effective ligands for transition metal ions for many years. They can form chelates (Xu et al., 2001) or act as bridging ligands (Bardaji et al., 1994). However, the chemistry of main-group metal complexes with dithiocarbamates has been less extensively studied, and only a few reports describing bismuth(III) dithiocarbamate complexes have appeared (Yin et al., 2003). As a continuation of our interest in sulfur-containing ligands, we report here the synthesis and structure of the title compound, (I).
The title compound, (I), is monomeric, with the Bi atom chelated by the S atoms of two pyrrolidine-1-dithiocarboxylate ligands and the N atoms of 2,2'-bipyridine. A nitrate ligand completes the coordination environment of the eight coordinated Bi atom (Fig. 1). The Bi atom is in a distorted pentagonal bipyramid environment, with atoms S1 and O2 in axial positions, and atoms S2, S3, S4, N3 and N4 in the equatorial plane. The remaining O atom (O1) of the nitrate ligand caps the O2/S2/N3 face of this pentagonal bipyramid, giving a highly distorted capped pentagonal bipyramid coordination geometry. One of the bidentate pyrrolidine-1-dithiocarboxylate ligands forms a significantly longer Bi—S bond [Bi1—S4 = 2.900 (4) Å] than the others in the complex. This variation in coordination strength is also signalled by the fact that the C6—S4 bond is significantly shorter than the other C—S bonds, suggesting some delocalization in the system. In addition, the chelating phenanthroline ligands are bonded to the Bi atom through two N atoms. The Bi1—N3 and Bi1—N4 distances fall in the same range as in other Bi/N complexes (Baraanyi et al., 1977).

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. |

Dithiocarbamates have been known as effective ligands for transition metal ions for many years. They can form chelates (Xu et al., 2001) or act as bridging ligands (Bardaji et al., 1994). However, the chemistry of main-group metal complexes with dithiocarbamates has been less extensively studied, and only a few reports describing bismuth(III) dithiocarbamate complexes have appeared (Yin et al., 2003). As a continuation of our interest in sulfur-containing ligands, we report here the synthesis and structure of the title compound, (I).
The title compound, (I), is monomeric, with the Bi atom chelated by the S atoms of two pyrrolidine-1-dithiocarboxylate ligands and the N atoms of 2,2'-bipyridine. A nitrate ligand completes the coordination environment of the eight coordinated Bi atom (Fig. 1). The Bi atom is in a distorted pentagonal bipyramid environment, with atoms S1 and O2 in axial positions, and atoms S2, S3, S4, N3 and N4 in the equatorial plane. The remaining O atom (O1) of the nitrate ligand caps the O2/S2/N3 face of this pentagonal bipyramid, giving a highly distorted capped pentagonal bipyramid coordination geometry. One of the bidentate pyrrolidine-1-dithiocarboxylate ligands forms a significantly longer Bi—S bond [Bi1—S4 = 2.900 (4) Å] than the others in the complex. This variation in coordination strength is also signalled by the fact that the C6—S4 bond is significantly shorter than the other C—S bonds, suggesting some delocalization in the system. In addition, the chelating phenanthroline ligands are bonded to the Bi atom through two N atoms. The Bi1—N3 and Bi1—N4 distances fall in the same range as in other Bi/N complexes (Baraanyi et al., 1977).
