title: Sodium cobalt aminomethylidenediphosphonate with a novel open framework structure.
abstract: This paper reports the synthesis and crystal structure of a cobalt aminomethylenediphosphonate compound NaCo(2)[NH(3)CH(PO(3))(PO(3)H(0.5))](2)(H(2)O)(2).xH(2)O (1). It shows a novel open framework structure in which layers of Co(2)[NH(3)CH(PO(3))(PO(3)H(0.5))](2)(H(2)O)(2) are connected by NaO(6) linkages. The magnetic studies show a dominant antiferromagnetic exchange between the Co(II) ions.
