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 octahedral coordination. Sac is O-bonded via the carbonyl group, while ppzea acts as an N,N′-bidentate chelating ligand. The molecules 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.
