Abstract

K2Co(HPO3)2·2H2O is a new phosphite within the K-T-H3PO3 system (T = divalent transition metal cation). Its structure can be described as a three-dimensional network made up of KO6 and HPO3 polyhedra, which share corners and edges. In the cavities of this framework, Co2+ ions are located in an almost regular octahedral oxygen coordination. An IR study has confirmed the presence of HPO3 hydrogenphosphite groups.
