本文描述了含5-（2-吡啶基）四唑、5-（3-氰基-4-吡啶基）四唑或5-（4-吡啶基）四唑配体的新的Mn（Ⅱ）配合物。配合物的制备通过相应的氰基吡啶与叠氮化钠在锰（II）盐的存在下的反应。所有的配合物已通过X-射线晶体学，其特征在于，这表明，5-（吡啶基）四唑配体可以通过任何类型的四唑残基中的氮原子或通过吡啶基配位到锰。在固态下，通过氢键网络（涉及水分子和四唑基）产生扩展的2D和3D结构。络合物的酸化产生相应的游离5-（吡啶基）-1H-四唑。
New Mn(II) complexes containing 5-(2-pyridyl)tetrazole, 5-(3-cyano-4-pyridyl)tetrazole or 5-(4-pyridyl)tetrazole ligands are described. The complexes are prepared by reaction of the corresponding cyanopyridines with sodium azide in the presence of Mn(II) salts. All the complexes have been characterized by X-ray crystallography, which reveals that 5-(pyridyl)tetrazole ligands can coordinate to Mn through either type of nitrogen atom in the tetrazole residue or via the pyridyl group. In the solid state, extended 2D and 3D structures are produced through networks of hydrogen bonding (involving water molecules and the tetrazolate residue). Acidification of the complexes produces the corresponding free 5-(pyridyl)-1H-tetrazole.
