[N(CH3)(4)](2)[Co2Mo6O12(OH)(4)(PO4)(HPO4)(2-)(H2PO4)].5H(2)O, a new one-dimensional molybdenum phosphate

The title compound, bis(tetramethylammonium) dicobaltio -mu-dihydrogenphosphato-mu-bis (hydrogenphosphato)-mu(6) -phosphato-tetrahydroxycyclohexamolybdate-(Mo-Mo) pentahydrate, was synthesized hydrothermally and crystallizes as a polymeric ionic complex with anionic chains, composed of [Mo6O12(OH)(3)(HxPO4)(4)](n-) clusters held together by Co2+ cations running parallel to the b axis. Neighbouring chains are linked by hydrogen bonds only via intervening [N(CH3)(4)](+) cations and water molecules.
