Cadmium bis­[dihydrogenphosphate(I)]

The structure of monoclinic (C2/c) cadmium bis­[di­hydrogen­phos­phate(I)], [Cd(H₂PO₂)₂], consists of layers located at x = 0 and . The Cd cation has a distorted octa­hedral coordination and dihydrogen­phos­phate(I) anions act as tridentate bridging ligands. The Cd atoms are on sites of twofold symmetry, while all other atoms are in general positions. The compound is isotypic with Ca(H₂PO₂)₂ [Goedkoop & Loopstra (1959). Ned. Tijdschr. Natuurkd. 25, 29-41].
