Resumo

BOOYSEN, Irvin N. et al. Oxo and oxofree rhenium(V) complexes with N,O-donor Schiff bases. S.Afr.j.chem. (Online) [online]. 2012, vol.65, pp. 174-177. ISSN 1996-840X.

The reaction between cis-[ReVO2I(PPh3)2] and H3duo (N-(2-hydroxybenzylidene)-5-amino-1,3-dimethyl uracil) led to the formation of the oxofree, imido compound, trans-[ReV(ddd)(Hduo)(PPh3)2]I (1) (H2ddd = 5,6-diamino-1,3-dimethyluracil). An oxo complex, cis-[ReV(bcp)OCl2(PPh3)](2) [Hbcp = N-(2-hydroxybenzylidene)-benzothiazole] was isolated from the reaction of trans-[ReOVCl3(PPh3)2]with Hbcp. The crystal structures of the compounds were determined by single crystal X-ray diffraction.

Palavras-chave : Rhenium(V); imido; oxo; crystal structure; spectral characterization.
