两个由双咪唑基配体构筑的锰、镉配合物的合成及晶体结构(英文)

Synthesis and Crystal Structure of Two Complexes of Manganese, Cadmium Assembled by Bis(imidazol) Ligands

通过水热法合成了2个金属-有机配位聚合物[Mn(dipha)(1,3-bix)]n·nH2O(1)和[Cd2(NIPH)2(bimb)2.5(H2O)]n·3nH2O(2)(H2dipha=2,2′-联苯二甲酸,1,3-bix=1,3-双(咪唑基-1-甲基)-苯,H2NIPH=5-硝基间苯二甲酸,bimb=1,4-双(咪唑基-1-甲基)-丁烷)。并对其进行了元素分析、红外光谱、热重和X-射线单晶衍射测定。这2个配合物通过氢键和π-π相互作用形成了超分子网状结构。此外还研究了配合物2的荧光性质。

Two metal-organic coordination polymers [Mn（dipha）（1,3-bix）]n·n H2O（1） and [Cd2（NIPH）2（bimb）2.5（H2O）]n·3n H2O（2）（H2dipha=2,2′-diphenic acid, 1,3-bix=1,3-bis（imidazol-1-ylmethyl）-benzene, H2NIPH=5-nitroisophthalic acid, bimb=1,4-bis（imidazol-1-yl）-butane） have been hydrothermally synthesized and structurally characterized by elemental analysis, IR spectrum, TG and single-crystal X-ray diffraction. They are further extended into a supramolecular network structure through hydrogen-bonding and π-π interactions. Moreover, the luminesent property of 2 has been investigated in the solid state.
