本文利用二吡啶[3,2-a∶2’,3’-c]并吩嗪-2-羧酸(HDPPZC)作为有机配体在水热条件下制备了配合物[CoCl_0.5(H₂O)_0.5(HDPPZC)₂](PW₁₂O₄₀)_0.5·3.5H₂O (1),利用X-射线单晶衍射、元素分析、紫外可见吸收光谱和差热分析对该化合物的结构进行了表征。单晶结构分析表明该晶体属于三斜晶系,P1空间群,晶胞系数a=1.036 0(2) nm,b=1.564 0(3) nm,c=1.656 0(3) nm,α=80.99(3)°,β=84.93(3)°,γ=85.44(3)°,V=2.6339(9) nm³,Z=1。配合物1是由零维离散结构通过氢键和π-π堆积形成的二维超分子结构。本文还研究了该化合物对罗丹明B的光催化降解性质。
