在氯仿溶液中，N-（2-氨基苯基）吡啶-2-甲酰胺L′与SnX 4（X = Cl，Br或I）或SnMe 2Cl 2脱水反应，合成了锡（IV）配合物[SnX 4L][L = 2-（2-吡啶基）苯并咪唑; X = Cl，Br或I]和[SnMe 2Cl 2L]. [SnMe_2Cl_2L]和[SnBr_4L]·0.5MeNO_2的X-射线晶体结构表明，两个分子中锡原子周围都存在畸变的八面体构型。配体L作为双齿螯合物，与杂环的吡啶型氮原子连接。[SnMe_2Cl_2L]中的氯原子是顺式的，而甲基是相互反式的。还报道了八面体锡（IV）配合物的红外光谱和穆斯堡尔谱以及X-射线结构和抗肿瘤（P388淋巴细胞白血病）数据的相关性。X-射线结构是第一个这样的金属配合物含有2-（2-吡啶基）苯并咪唑的报道。
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.
