Bis(n,n′-bis(2-hydroxyethyl)ethylenediamine)nickel(ii) saccharinate: Synthesis, characterization and crystal structure

Abstract

A new nickel(II) saccharinate (sac) complex containing N,N'-bis(2-hydroxyethyl)ethylenediamine (bishydeten), [Ni(bishydeten)(2)](sac)(2), has been synthesized and characterized by elemental analysis, FTIR. and single crystal X-ray diffraction. The title complex consists of a [Ni(bishydeten)(2)](2+) cation and two sac anions. In the complex cation, the nickel(II) ion is coordinated by two neutral bishydeten ligands, leading to a distorted octahedral NiN4O2 coordination, while both sac anions remain outside the coordination sphere. In the crystal, the complex cations and sac anions are connected by an extensive network of N-H center dot center dot center dot N, N-H center dot center dot center dot O, O-H center dot center dot center dot O and C-H center dot center dot center dot O hydrogen bonds into a three-dimensional supramolecular lattice.
