title: Dipotassium diaqua-bis(methyl-enedi-phospho-nato-κO,O')cobaltate(II).
abstract: In the title complex, K(2)[Co(CH(4)O(6)P(2))(2)(H(2)O)(2)], the asymmetric unit contains two K(+) cations and two half-anions in which the Co atoms lie on inversion centers. The Co(II) ions assume an octa-hedral CoO(6) coordination geometry. In the crystal, a three-dimensional network is formed through O-H⋯O hydrogen-bond inter-actions as well as inter-molecular inter-actions between the K(+) cations and neighbouring O atoms.
