B. P. Baranwal*, S. S. Das, Poonam Singh Chemistry Department, University of Gorakhpur, Gorakhpur 273009 India Z. Naturforsch. 52b, 1039-1042 (1997); received July 7, 1997 Cobalt(II) Derivatives, Cyclic Phosphazenes, IR Spectra Chlorine atoms of hexachlorocyclotriphosphazene were substituted with -NH.C2H5, -NH.CH 2C6H5 and -O C 2Hs to yield organotriphosphazene ligands. Anhydrous cobalt(II) chloride formed a number of addition complexes with these ligands in different stoichiomet­ ric ratios. On the basis of electronic and IR spectra, magnetic moment, conductivity meas­ urements and molecular weight determination, structures of these complexes have been sug­ gested. The complexes were screened for their antifungal activities against Aspergillus flavus and Aspergillus niger.
