A novel 1D organic-inorganic hybrid based on alternating heteropolyanions [GeMo12O40] and isopolyanions [Mo6O22]

A novel one-dimensional (1D) coordination polymer {Cu(2,2′-bpy)}₆(Mo₆O₂₂)]GeMo₁₂O₄₀]·H₂O (2,2′-bpy=2,2′-bipyridine), which represents the first example of 1D organic-inorganic hybrid based on a Keggin-type heteropolyanion GeMo₁₂O₄₀]⁴⁻ and an unprecedented isopolyanion Mo₆O₂₂]⁸⁻, has been hydrothermally synthesized and characterized by single crystal X-ray diffraction. Crystal data: C₆₀H₅₀Cu₆GeMo₁₈N₁₂O₆₃, monoclinic, P2₁/c, a=13.9344(3), b=20.0329(3), c=17.2151(3) Å; β=94.0220(10)°, V=4793.70(15) Å³, T=293(2) K; Z=2.
