Hydrothermal synthesis and crystal structure of a novel two-dimensional organic-inorganic hybrid copper molybdate with mixed organodiamine and dicarboxyl ligands

摘要

An unusual compound, [{Cu(2,2'-bpy)}(2)(tp)Mo4O13] (tp=terephthalate) 1, has been hydrothermally synthesized and structurally characterized by the elemental analyses, IR spectrum, X-ray photoelectron spectrum, TG analyses and the single crystal X-ray diffraction. The structure of I exhibits a layered network built up from bimetallic one-dimensional ribbons bridged by dicarboxylate ligands. Compound 1 represents the first hybrid molybdates composed of mixed organodiamine and dicarboxylate ligands. Crystal data for compound 1: triclinic, space group P (1) over bar, a = 7.3748(15) Angstrom, b = 9.9692(2) Angstrom, c = 12.0692(2) Angstrom, alpha = 69.223(3)degrees beta = 76.123(3)degrees, gamma = 76.623(3)degrees: V = 794.83(3) Angstrom(3); Z = 1, R (final) = 0.0688. The data were collected on a Rigaku R-AXIS RAPID IP diffractometer at 293 K using graphite-monochromated MoKalpha radiation (lambda = 0.71073 Angstrom) and oscillation scans technique in the range 1.83degrees < theta < 27.48degrees.
