The new tripodal ligand tris-[{2-benzaldehyde}-oxoethyl}amine]-thiosemicarbazone, N[CH2-CH2-O-{o-C6H4- CH=N-NH-C(=S)-NH2}}3 (abbreviated as H3L) on reaction with silver(I) acetate in 3:1 (M:L) mol ratio in ethanol forms {Ag5L(OAc)2} (1). which in presence of excess triphenylphosphine (PPh3) in chloroform-ethanol mixture yield. {Ag5L(OAc)2(PPh3)12}(2) (L is deprotonated). Similarly, reactions of silver(I) acetate with salicylaldehyde thiosemicarbazone (H2stsc), furan-2-carbaldehyde thiosemicarbazone (Hftsc) and pyrrole-2-carbaldehyde thiosemicarbazone (Hptsc) in presence of PPh3 in ethanol-chloroform form [AgL(PPh3)n] complexes (3-5)[L (n) = Hstsc (3): ftsc (4); ptsc (5): thiosemicarbazones are monodeprolonated]. The complexes (1-5) have been characterised by their physical properties, analytical data, IR and UV spectroscopic studies.
