Diaquabis(ethylenediamine)nickel(II) Bis(p-toluenesulfonate) Monohydrate 층상 화합물의 합성과 구조 분석

Abstract

The layer structure of the title compound, [Ni(en)2(H2O)2](CH3C6H4SO3)2(H2O) (en = ethylenediamine), consists of discrete cations, anions, and solvate water molecules linked by a hydrogen bonding network. The central Ni atom of the cation layer has a slightly distorted octahedral coordination geometry with the ethylenediamine ligands functioning as a N,N'-bidentate and the water ligands bonding through oxygen in a trans arrangement. The p-toluenesulfonate of the anion layer has an alternate sulfonate group directed toward opposite side of the cation layer. This layer structure is stabilized by a hydrogen bond involving the O atoms of the sulfonate, the water ligand, solvate water molecule, and the N atoms of the ethylenediamine.
