Abstract

Chlorine atoms of hexachlorocyclotriphosphazene were substituted with -NH.C2H5, -NH.CH2C6H5 and -OC2H5 to yield organotriphosphazene ligands. Anhydrous cobalt(II) chloride formed a number of addition complexes with these ligands in different stoichiometric ratios. On the basis of electronic and IR spectra, magnetic moment, conductivity meas­urements and molecular weight determination, structures of these complexes have been sug­gested. The complexes were screened for their antifungal activities against Aspergillus flavus and Aspergillus niger.
