Cs2[M(H2O)6]3(HPO3)4, M=Co (1) Ni (2) are two isostructural phosphites. The structure consists of isolated layers parallel to (001) crystallographic plane. The HPO3 phosphite ions are linked to the Cs(H2O)8 and M(H2O)6 polyhedra via hydrogen bonds. The 3D framework is build upon these layers. IR spectra of the title compounds present the HPO3 characterizing bands. TG curves document the process of the full dehydration.
