A novel 1D ladder-like organic–inorganic hybrid compound [(Cu(bIz)2)]2[{Cu(bIz)2}2Mo8O26] (bIz=benzimidazole)

A novel organic–inorganic hybrid compound [(Cu(bIz)2)]2[{Cu(bIz)2}2Mo8O26] (1) has been synthesized from solvothermal reaction of benzimidazole, NaMoO4 and MoO3 with CuCl2·2H2O in H2O/CH3OH solution and characterized by single-crystal X-ray diffraction analysis. Crystallographic data for 1: monoclinic, space group C2/c, a=23.6823(2) Å, b=20.2669(5) Å, c=16.0220(3) Å, β=109.030(1), Z=8, V=7269.8(2) Å3. The compound consists of a centrosymmetric β-octamolybdate-supported complex anion [{Cu(bIz)2}2Mo8O26]2−, and two bis-bIz coordinated Cu(I) cations. The hydrogen bonds between [{Cu(bIz)2}2Mo8O26]2− anions generate a interesting 1D ladder. TG analysis, UV–Vis spectra and fluorescent spectroscopy of the compound were also studied.
