CRYSTAL-STRUCTURE AND SPECTROSCOPIC BEHAVIOR OF -BIS(5,7-DICHLORO-8-HYDROXYQUINOLINATO)VANADIUM(V)

The title compound, a new example of an inorganic ester-like complex, was characterized by spectroscopic and X-ray crystallographic methods. It crystallizes in the triclinic space group <P(1)over bar>(a = 9.413 (2), b = 10.595(3), c = 11.783(2) Angstrom, alpha = 103.59(2), beta = 101.98(2), gamma = 99.40(2)degrees, Z = 2). The structure was solved e mploying 2902 independent reflections with I > 2 sigma(1) by direct an d Fourier methods and refined by a full-matrix least-squares fit to R- 1 = 0.049. Infrared and Raman spectra of the solid compound and the el ectronic absorption spectra of its acetonitrilic and ethanolic solutio ns were recorded and are briefly discussed.
