Crystal structure of bis-[N,N-bis-(2-hydroxy-eth-yl)glycinato-κ(3) O (1),N,O (2)]cobalt(II) monohydrate.

ABSTRACT: The title compound, [Co(C6H12O4)2]·H2O, was prepared by mild heating of an aqueous solution. The Co(II) ion has a slightly distorted octahedral coordination environment which is defined by two N atoms occupying the apical position, while the equatorial plane is furnished by two hy-droxy O atoms and two carboxyl-ate O atoms. The four hy-droxy O atoms from two distinct N,N-bis-(2-hy-droxy-eth-yl)glycine (bicH2 (-)) ligands act as hydrogen-bond donors with two carboxyl-ate O atoms as acceptors to form O-H⋯O hydrogen-bonded layers extending parallel to (100). In addition, the guest water mol-ecule acts as both a hydrogen-bond donor and acceptor, so that each Co(bicH2)2 mol-ecule is connected simultaneously to six neighbouring Co(bicH2)2 and two guest water mol-ecules by hydrogen bonding.
