Bis(2,2',2''-nitrilotriacetamide-[kappa]3O,N,O')cobalt(II) dinitrate tetrahydrate

J.-W. Ran and J. Pei

Abstract: In the centrosymmetric title compound, [Co(C6H12N4O3)2](NO3)2·4H2O, the CoII ion, lying on an inversion center, is O,N,O'-chelated by two nitrilotriacetamide molecules, forming a distorted octahedral geometry. In the crystal, extensive O-H...O and N-H...O hydrogen bonds link the complex cations, nitrate anions and lattice water molecules into a three-dimensional network.
