Diammonium diaquabis(malonato-κ2O,O′)cobaltate(II) dihydrate

Abstract

The title complex, (NH4)2[Co(C3H3O4)2(H2O)2]·2H2O, features a six-coordinate Co atom located on a center of symmetry. The octahedral O6 coordination geometry is defined by two bidentate malonate ligands and two water molecules, with the latter in a trans configuration. The molecules are linked through O—H...O and N—H...O hydrogen-bonding interactions, forming a three-dimensional supramolecular network.
