Assembly of a new inorganic–organic frameworks based on [Sb4Mo12(OH)6O48]10− polyanion

• A novel inorganic–organic hybrid compound based molybdoantimonate.
• X-ray diffraction, infrared, UV–visible spectroscopy.
• Cyclic voltammetry and TG–DTA analysis.

A new organic–inorganic hybrid material, (C4N2H7)8[K(H2O)]2[Sb4Mo12(OH)6O48]⋅16H2O (1) has been isolated by the conventional solution method and characterized by elemental analysis, single-crystal X-ray diffraction, infrared spectroscopy, UV–visible spectroscopies, cyclic voltammetry and TG–DTA analysis. The compound crystallizes in the triclinic space group P − 1 with a = 13.407(6) Å, b = 13.906(2) Å, c = 14.657(7) Å, α = 77.216(9)°, β = 71.284(6)°, γ = 71.312(3)° and Z = 1. The crystal structure exhibits an infinite 1D inorganic structure built from [Sb4Mo12(OH)6O48]10− clusters and potassium cations; adjacent chains are further joined up hydrogen bonding interactions between protonated 2-methylimidazolim cations, water molecules and polyoxoanions to form a 3D supramolecular architecture.
