摘要
The novel mixed-ligand neutral compound [Mo3O4(C2O4)2bipy-(H2O)3]·EtOH·2H2O(bipy = 2,2′-bipyridine) has been prepared by the reaction of oxalic acid elution of Mo(IV) and bipy, and characterized by single-crystal X-ray diffraction analysis and IR. The crystal is of triclinic, space groups P1^- with a = 9.5520(2), b = 10.3730(1), c = 13.5722(2)A, a = 74.940(12),β = 80.772(14),γ= 69.898(11)°, V = 1215.73(11)A^3, Z = 2, C16H24Mo3N2O18, Mr = 820.19, Dc = 2.241 g/cm^3,μ = 1.616 mm^-1, F(000) = 808, T = 293(2) K, the final R = 0.0424 and wR = 0.0939 for 4119 observed reflections with I 〉 2σ(I). The trinuclear unit is coordinated by mixed ligands of oxalate and bipy. The intermolecular hydrogen bonding interactions among adjacent [Mo3O4(C2O4)2·bipy(H2O)3] extend the compound into a three-dimensional supramolecular framework. The uncoordinated water molecules and ethal molecules act as space-fillers and consolidate the whole architecture through hydrogen bonding interactions.
