双吡唑甲烷配合物的合成、晶体结构及性质

The synthesis,crystal structure and properties of Bis(pyrazol)methane complexes

采用溶液法成功地合成两种新的双吡唑甲烷配合物[Ag_(2)(bpm)_(2)](NO_(3))_(2)(1)和[Pd(bpm)2]Cl·H_(2)O(2),(bpm:bis(pyrazol)methane),通过红外光谱、元素分析和X-射线单晶衍射等手段确定双吡唑甲烷配合物的晶体结构。X-射线单晶衍射研究表明,配合物1是[Ag_(2)]二聚体,通过氢键作用组装成一维链状结构;配合物2是Pd(II)单核结构,通过氢键形成三维超分子结构。对目标配合物的室温荧光光谱以及Hirshfeld surface表面作用力,研究结果表明,与自由配体bpm相比,配合物的荧光轻微蓝移;配合物1和2的主要相互作用分别是O…H/H…O和H…H接触。

Two new Ag(I)and Pd(II)complexes[Ag_(2)(bpm)_(2)](NO_(3))2(1)and[Pd(bpm)_(2)]Cl·H_(2)O(2)(where bpm is bis(pyrazol)methane)were successfully synthesized by solution method.The complex 1 is a[Ag 2]dimer and assembled into a 1D chain by hydrogen bonding interactions.The complex 2 is a Pd(II)monomer and forms into 3D supramolecule by hydrogen bonds.All structures have been determined by single-crystal X-ray diffraction,and established by FT-IR and solid state fluorescent spectroscopy.Hirshfeld surface analysis reveals that the main interactions for complexes 1 and 2 are O…H/H…O and H…H contacts,respectively.
