Synthesis and characterization of some new heterochelates of chromium(III)

Some new chromium(III) heterochelates having different coordination environment, synthesized by the reactions of [Cr-III(L-1)(Py)Cl]2H(2)O, [Cr-III(L-2)(Py)Cl]H2O and [Cr-III(L-3)(2)(Py)Cl] (ClO4)(2) (where L-1 and L-2 are dianions of quadridentate schiff bases and L-3 is a neutral bidentate schiff base) with acetylacetone (Hacac), glyoxime (Hgly), salicylaldehyde (Hsal), N-Phenylsali cyaldimine (Hsalan), anthranilic acid (Hana), picolinic acid (Hpica), orthoaminophenol (Hoap) and orthoaminothiophenol (Hoatp) by a common general route are reported. The elemental analyses, molar conductances, magnetic susceptibilities, molecular weights and spectroscopic data (IR, UV-vis) characterize the newly synthesized complexes. The stereochemistry of the complexes has also been discussed.
