新型二维有机膦酸镍化合物的合成、 晶体结构与气体吸附性能

Abstract

A novel metal organo-diphosphonate compound constructed 2D layers with alkaline gas adsorption property has been synthesized through hydrothermal method. The compound is isomorphous and crystallizes in the Monoclinic, C2/c space group. The metal ions are six-coordinate with four oxygen atoms coming from phosphonate and coordinated aqua molecules and two nitrogen atoms coming from 4, 4'-bpy. The two oxygen atoms of phosphonate are uncoordinated which indicated that the structure could absorb some alkaline gas.
