Disodium diaqua-bis-(methyl-enedi-phos-pho-nato-?O,O')cobaltate(II) dihydrate.

ABSTRACT: In the title compound, Na(2)[Co(CH(4)O(6)P(2))(2)(H(2)O)(2)]·2H(2)O, the asymmetric unit is composed of one methyl-enediphospho-nate ligand and one water mol-ecule, which both are coordinated to a Co(II) atom, as well as a non-coordinated water mol-ecule and a sodium cation. The Co(II) atom occupies a special position on a crystallographic inversion centre. The slightly distorted Co(II)O(6) octa-hedral coordination environment is composed of two bidentate methyl-enediphospho-nate ligands and two coordinated water mol-ecules in trans positions. The sodium ion is octa-hedrally coordinated to six O atoms with Na-O distances ranging from 2.3149?(12) to 2.6243?(12)?Å. An extensive three-dimensional network of inter-molecular as well as intra-molecular O-H?O and C-H?O hydrogen bonding inter-acions is present.
