Diammonium diaquabis(malonato-²O,O')cobaltate(II) dihydrate

H. Xu and F. Wang

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-HO and N-HO hydrogen-bonding interactions, forming a three-dimensional supramolecular network.
