title: trans-Bis[2-(piperazin-1-yl)-ethan-amine]-bis-(saccharinato)cobalt(II).
abstract: In the centrosymmetric title complex, [Co(C(7)H(4)NO(3)S)(2)(C(6)H(15)N(3))(2)], the Co(II) 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.
