The crystal structure has been determined by X-ray single-crystal diffraction analysis. It crystallizes in monoclinic space group C2/c with a = 12.5768(4), b= 16.5601(4), c = 19.3574(7) , β = 99.879(1)°, V = 3971.3(2)3, D_c = 1.589 g/cm3, μ= 1.157 mm -1, F(000)=1932, Z=4, R = 0.055, wR = 0.1539 (I2σ(I)). This compound has an unusual coplanar V_3O core with a C_2 axis passing through O(1), V(1), O(10): one V-μ_3O is short (1.628 ), the other two are longer (2.381 ). It was characterized by IR, 1H NMR, and EPR spectra. It was unstable and the decomposition process of this compound was studied using IR spectroscopy.展开更多

F(000) = 1040, λ(MoKa) =14. 0 cm-1. The final R=0. 094, Rw= 0. O95 for 13O4 observed reflections with I≥3. 0σ (I). The result of structure analysis indicates that the framework of this com-pound is a typical trimeric oxo ccntered carboxylato compound.展开更多
