摘要

Bis(acetylacetonato)oxovanadium C10H14O5V (I) and (S)-[2-(N-salicylidene)aminopropionate]oxovanadium monohydrate C10H9NO5V (II) are synthesized. The crystal structures of compounds I and II are determined using single-crystal X-ray diffraction. Crystals of compound I are triclinic, a = 7.4997(19) angstrom, b = 8.2015(15) angstrom, c = 11.339(3) angstrom, alpha = 91.37(2)degrees, beta = 110.36(2)degrees, gamma = 113.33(2)degrees, Z = 2, and space group P1. Crystals of compound II are monoclinic, a = 8.5106(16) angstrom, b = 7.373(2) angstrom, c = 9.1941(16) angstrom, 101.88(1)degrees, Z = 2, and space group P2(1). The structures of compounds I and II are solved by direct methods and refined to R-1 = 0.0382 and 0.0386, respectively. The oxovanadium complexes synthesized are investigated by vibrational spectroscopy. (c) 2005 Pleiades Publishing, Inc.
