Crystals of the title compound (I) were synthesized using hydrothermal method in a 23 ml Teflon-lined Parr bomb, which was then sealed. Tin dioxide (30.1 mg, 0.2 mmol), 4,4'-bipyridine (93.6 mg, 0.6 mmol), nitric acid (0.2 mol/l, 4 ml) and distilled water (2 g) were placed into the bomb and sealed. The bomb was then heated under autogenous pressure for 7 d at 413 K and allowed to cool at room temperature for 24 h. Upon opening the bomb, a clear colorless solution was decanted from small colorless crystals. These crystals were washed with distilled water followed by ethanol, and allowed to air-dry at room temperature. Powder X-ray diffraction was conducted on the sample.
H atoms were positioned geometrically, with C—H = 0.93 Å for aromatic H and constrained to ride on their parent atoms, with Uiso(H) = 1.2Ueq(C).
In recent years, the researches on tin complexes draw increasing attention owning to their potential applications as photovoltaic materials, holographic recording system and biological activities (Jiang & Ozin, 1998; Valiukonis et al., 1986; Hencher et al., 1982; Bandoli et al., 1992, 1993), solar control devices (Nair & Nair, 1991) and semiconductor materials. Mononuclear or binuclear tin materials are important candidates as molecular precursors to prepare tin film materials by chemical vapour deposition (CVD)(Barone et al., 2002). We report herein the crystal structure of the title compound, (I).
In the molecule of (I) (Fig. 1), the ligand bond lengths and angles are within normal ranges (Allen et al., 1987). The ten-coordinate environment of the Sn atom is completed by two N atoms of 4,4'-bipyridine ligands and eight O atoms of four NO3- ligands (Table 1). The Sn—O bond lengths are in the range 2.378 (5) to 2.538 (5) Å. The Sn—N bond length is 2.601 (5) Å. The C—H···O hydrogen bonds link the mononuclear complex into a supramolecular network structure (Fig. 2).

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. |

In recent years, the researches on tin complexes draw increasing attention owning to their potential applications as photovoltaic materials, holographic recording system and biological activities (Jiang & Ozin, 1998; Valiukonis et al., 1986; Hencher et al., 1982; Bandoli et al., 1992, 1993), solar control devices (Nair & Nair, 1991) and semiconductor materials. Mononuclear or binuclear tin materials are important candidates as molecular precursors to prepare tin film materials by chemical vapour deposition (CVD)(Barone et al., 2002). We report herein the crystal structure of the title compound, (I).
In the molecule of (I) (Fig. 1), the ligand bond lengths and angles are within normal ranges (Allen et al., 1987). The ten-coordinate environment of the Sn atom is completed by two N atoms of 4,4'-bipyridine ligands and eight O atoms of four NO3- ligands (Table 1). The Sn—O bond lengths are in the range 2.378 (5) to 2.538 (5) Å. The Sn—N bond length is 2.601 (5) Å. The C—H···O hydrogen bonds link the mononuclear complex into a supramolecular network structure (Fig. 2).
