Dicaesium diaqua­bis­(methyl­ene­diphospho­nato-κ2 OO′)cobaltate(II)

摘要

The asymmetric unit of the title compound, Cs2[Co(CH4O6P2)2(H2O)2], is comprised of one bidentate methyl­enediphospho­nate ligand and one water mol­ecule which are coordinated to the Co^II atom, as well as a caesium counter-cation. The Co atom occupies a special position on a crystallographic inversion center. The caesium ion is octa­hedrally coordinated by six O atoms with Cs—O distances ranging from 3.119 (2) to 3.296 (2) Å. A three-dimensional network is formed through O—H⋯O hydrogen bonds.
