[N(CH₃)₄]₂[Co₂Mo₆O₁₂(OH)₄(PO₄)(HPO₄)₂(H₂PO₄)].5H₂O, a New One-Dimensional Molybdenum Phosphate

The title compound, bis(tetramethylammonium) dicobaltio-μ-dihydrogenphospahto-μ-bis(hydrogenphosphato)-μ₆-phosphato-tetrahydroxycyclohexamolybdate(Mo—Mo) pentahydrate, was synthesized hydrothermally and crystallizes as a polymeric ionic complex with anionic chains, composed of [Mo₆O₁₂(OH)₃(H_xPO₄)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.
