The structure consists of chains of Ca2+ and Sn 4+ cations in octahedral sites with -3 symmetry bridged by bidentate hypophosphite anions. The chains are hexagonally close packed along [001]. The discovery of the compound and the successful structure refinement provides strong evidence that an isostructural compound, originally described as the mixed-valence compound, Ge2[H2PO2]6 [Weakley (1983). J. Chem. Soc. Pak. 5, 279-281], must be reformulated as Ca[Ge(H2PO2)6]. |
