【 摘 要 】

A series of homo binuclear complexs of the type [M2(L/L¡¯)(NO3)n].mH2O, [where M=UO2 2+, Th4+, ZrO2+] and [(VO)2(L/L¡¯)(SO4)2]¡¤2H2O, L=1,5,6,9,12,15,16,20 octaaza-7,813,14-tetraphenyl-2,4,17,19-tetramethyl-1,4,6,8,12,14,16,19- docosaoctene (OTTDO) or L¡¯=10:11;21:22-dibenzo-1,5,6,9,12,15,16,20-octaaza-7,813,14-tetraphenyl-2,4,17,19-tetramethyl- 1,4,6,8,12,14,16,19-docosaoctene (DOTTOT), n=4 for UO2 2+, ZrO2+ n=8 for Th4+ m=1,2,3 respectively, have been synthesized in template method from ethylenediamine/orthophenylene diamine, benzil monohydrazone and acetyl acetone and characterized on the basis of elemental analysis, thermal analysis, molar conductivity, magnetic moment, electronic, infrared, 1H-NMR studies. The results indicate that the VO(IV) ion is penta co-ordinated yielding paramagnetic complexes; UO2(VI), ZrO(IV) ions are hexa co-ordinated where as Th(IV) ion is octa co-ordinated yielding diamagnetic complexes of above composition. The fungi toxicity of the ZrO(IV) and VO(IV) complexes against some fungal pathogen has been studied.
