Studies on chromium(III) complexes of some furoylhydrazones

摘要

Chromium(III) complexes of the compositions [Cr(L)(HL)Cl](2)Cl-2 [HL = 2-acetylthiophene-2-furoylhydrazone (Hatfh), 2-acetylfuran -2-furoylhydrazone (Haffh). 2-acetylpyridine-2-furoylhydrazone-(Hapfh), (o) under bar-hydroxyacetophenone-2-furoylhydrazone (H(2)hafh]l. Cr-2(L)(3)(OH)(3)[H2O)(2) [HL = Hatfh, Haffh, Hapfh] and [Cr(L)(3)](2) [HL = H(2)hafh)] have been prepared and characterized on the basis of elemental analyses. molar conductance, magnetic susceptibility and IR spectral studies. Electronic and emission spectra show a decrease in the interelectronic repulsion while emission spectra are indicative of the absence of centro-symmetry around Cr3+. [References: 18]
