The tin(IV) complexes [SnX4L] [L = 2-(2-pyridyl)benzimidazole; X = Cl, Br or I] and [SnMe2Cl2L] were prepared by a dehydration reaction of N-(2-aminophenyl)pyridine-2-carboxamide L' with either SnX4 (X = Cl, Br or I) or SnMe2Cl2 in chloroform solution. The X-ray crystal structures of [SnMe2Cl2L] and [SnBr4L].0.5MeNO2 show a distorted octahedral geometry around the tin(IV) atom in both molecules. The ligand L acts as a bidentate chelate with ligated atoms being the pyridine-type nitrogens of the heterocyclic rings. The chlorine atoms in [SnMe2Cl2L] are cis while the methyl groups are trans to each other. Infrared and Mossbauer spectra and a correlation of X-ray structural and anti-tumour (P388 lymphocytic leukaemia) data for the octahedral tin(IV) complexes are also reported. The X-ray structures are the first such reported for metal complexes containing 2-(2-pyridyl)benzimidazole. (EN)
