Trans-Bis[2-(Piperazin-1-yl)ethanamine]bis(Saccharinato)cobalt(II)

Abstract

In the centrosymmetric title complex, [Co(C7H4NO3S)2(C6H15N3)2], the CoII ion is coordinated by two saccharinate (sac) anions and two neutral 2-piperazin-1-ylethanamine (ppzea) ligands, showing a distorted octa-hedral coordination. Sac is O-bonded via the carbonyl group, while ppzea acts as an N,N′-bidentate chelating ligand. The mol-ecules are connected by N - H⋯N and N - H⋯O hydrogen bonds, forming a linear chain running parallel to the crystallographic a axis. The compound is isostructural with the reported Ni, Zn, and Cd analogues. © International Union of Crystallography 2008.
