在水热条件下,合成配合物[Ni(ptc)(bipy).4.5H2O]单晶,(H3ptc为2,4,6-吡啶三羧酸,bipy为4,4’-联吡啶).配合物晶体属于三斜晶系,P-1空间群.配体H3ptc上的一个氮原子和两个羧基氧原子与Ni2+螯合配位,而另一个配体bipy的一个氮原子为端基配位,金属Ni2+离子的轴向位置被两个水分子占据,形成一个六配位扭曲八面体构型.配合物分子之间通过分子内和分子间的氢键作用进一步形成三维空间网状结构.
Under hydrothermal conditions, the complex [Ni (ptc) (bipy) · 4.5H2O] was synthesized, (H3ptc is 2,4,6-pyridinetricarboxylic acid and bipy is 4,4’-bipyridine) The material crystal belongs to the triclinic, P-1 space group, one nitrogen atom and two carboxyl oxygen atoms on ligand H3ptc are chelated to Ni2 +, and one nitrogen atom on the other ligand bipy is terminal coordination , The axial position of metal Ni2 + ions is occupied by two water molecules, forming a hexacoordinated distorted octahedron. The complex molecules further form a three-dimensional network structure through intramolecular and intermolecular hydrogen bonding.
