SYNTHESIS AND REACTIVITY OF CHROMIUM AND MANGANESE DIBROMOACETATES AND THEIR COMPLEXES WITH ORGANIC BASES
Complexes of composition CrCl(Br2CHCOO)2, Cr3O(Br2CHCOO)6Cl, [Cr3O(Br2CHCOO)6(Br2CHCOOH)3Cl], Cr(Br2CHCOO)3, Cr(Br2CHCOO)3.Py, Cr(Br2CHCOO)3.Q, Cr(Br2CHCOO)3(C2H5)3N, [Cr3O(Br2CHCOO)6(NH3)3]Cl.5NH3, Mn(Br2CHCOO)2, Mn(Br2CHCOO)2.2Py, Mn(Br2CHCOO)2.2Q, Mn(Br2CHCOO)2.2(C2H5)3N and (Me4N)2Mn(Br2CHCOO)4 have been synthesized. All these compounds have been characterized by elemental analysis, molar conductance, infra-red, reflectance and thermo-gravimetric studies. These studies indicate the hexa co-ordination of chromium and manganese in these compounds having octahedral geometry and suggest the formation of polymeric structures. Further attempts are in progress to isolate the single crystal of these complexes in order to throw more light on the structure of these complexes from single crystal x-ray studies.
