The preparation and characterization of some new chromium(III) complexes, s
ynthesized by the reactions of different chromium salts with 1,3-diaminopro
pane-2-ol, (L), neutral bidentate Schiff bases N,N'-ethylenebis(benzophenon
eimine) (L-1), N,N'-ethylenebis(acetophenoneimine) (L-2) and N-phenyl-2-(2-
acetylpridyl)imine (L-3) under varied reaction conditions are reported. The
reactions of the isolated complex [Cr(L)(2)(Py)(Cl)]Cl-2.H2O with acetylac
etone (Hacac), glycine (Hgly), N-phenylsalicylaldimine (Hsalan) and N-pheny
l-orthohydroxyacetophenoneimine (Hohapan) yield heterochelates of the type
[Cr(L)(2)(lig)]Cl-2.H2O (where lig = mono anion of Hacac, Hgly, Hsalan or H
ohapan). The stereochemistry of the isolated complexes has been discussed.
