Studies on Some Complexes of Pd(0), Pt(0) Rh(I) and Zr(IV) with Physiologically Active 4-Amino-5-Mercapto-3-Methyl-s-Triazole

Abstract

Some new complexes of Pd(0), Pt(0), Rh(I) and Zr(IV) ions with 4-

amino-5-mercapto-3-methyl-s-triazole (AmMTH) have been prepared and

investigated using various physico-chemical methods. Pd(0) and Pt(0)

complexes have been prepared from Malatesta compounds Pt(PØ₃)₄ and

Pd (PØ₃)₄ and Rh(I)-complexes are prepared starting from Wilkinson's

catalyst (PØ₃)₃RhCl in benzene medium. However, Zr(IV) complexes have

been isolated in ethanolic medium. Tetrahedral structure of Pd(0), Pt(0),

square- planar for Rh(I) and distorted octahedral structure for Zr(IV) complexes

have been assigned reasonably using various physico-chemical data.
