摘要
The title compound (C_ 24H_ 40Cl_6O_ 16V_3, M_r = 950.08) was synthesized from the reaction of VCl_3 and NaO_2CEt in CHCl_3 and THF. 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.
