Synthesis And Characterisation Of Ruthenium(Iii),Rhodium(Iii),Palladium(Ii),Platinum(Ii,Iv),Osmium(Viii)Complexes With P-Naphthaldehyde-4-Benzamido Thiosemicarbazonje And P-Acetamido Benzaldehyde-4-Benzamido Thiosemicarbazone

摘要

Metal complexes with beta-Naphthaldehyde-4-benzamido thiosemicar-bazone(NBTSC)and p-acetamido benzaldehyde-4-benzamido thiosemicarbazone(ABBTSC)of the type M.L.CI_2;[M~1L_2CI_2]CI_2,[M~IIL_2CI_2]CI;M~IIIL_2CI_4 where M=Pd(II),Pt(II);M~I=Pt(IV),M~II=Ru~+3/Rh~+3,M~III=OSO_2 and L=(C_19H_16N_4OS)/(C_17H_17N_5O_2S)have been isolated and characterised using different physico-chemical methods.Pd(II)/Pt(II)-complexes have square planar geometry while other platinum metals have octahedral geometry as revealed by magnetic and electronic spectral studies.Both are neutral ligands having-CH=N and >C=S as the coordinating sites.
