Hydrothermal Synthesis and Structural Characterization of a Novel Organic‐Inorganic Hybrid Compound {[Cu (2, 2′‐bpy)2]2‐Mo8O26}

Abstract

AbstractA novel organic‐inorganic hybrid compound {[Cu(2, 2′‐bpy)2]2Mo8O26 } has been hydrothermally synthesized and structurally characterized by single‐crystal X‐ray diffraction. The compound crystallizes in the orthorhombic space group, Pna21 with a = 2.4164(5), b = 1.8281(4), c= 1.1877(2) nm, V = 5.247(2) nm3, Z = 4, and final R1, =0.0331, wR2, = 0.0727. The structure consists of discrete { [ Cu (2, 2′‐bpy)2]2Mo8O26} dusters, constructed from a β‐octamolybdate subunit [Mo8O26]4‐ covalently bonded to two [Cu(2, 2′‐bpy)2]2+ coordination complex cations via bridging oxo groups. In addition, the spectroscopic properties and thermal behavior of this compound have been investigated by spectroscopic techniques (UV‐vis, IR, Raman and EPR spectra) and TG analysis.
