1D Polyoxometalate‐based Inorganic‐Organic Hybrid Derived from ß‐Octamolybdate — Synthesis and Crystal Structure of [Co II (2, 2′‐bipy) 2 ] 2 [Mo 8 O 26 ]

A polyoxometalate‐based inorganic–organic hybrid compound [Co II (2, 2′‐bpy) 2 ] 2 [Mo 8 O 26 ] ( 1 ) was synthesized by hydrothermal methods and structurally characterized by IR spectrum, TG analysis and X‐ray diffraction. The compound crystallizes in the monoclinic system, space group P2 1 /n, a = 10.0681(2), b = 16.4467(2), c = 15.7838(3) Å, β = 100.046(1)°, V = 2573.52(8) Å 3 , Z = 2. The structure of 1 is built up from β‐[Mo 8 O 26 ] 4− subunits covalently linked via [Co II (2, 2′‐bpy) 2 ] 2+ fragments into a infinite 1D {[Co II (2, 2′‐bpy) 2 ] 2 [Mo 8 O 26 ]} ∞ polymer.
