Abstract:

Thermal decomposition of Co(III), Cu(II), Ni(II), Pd(II), and Pt(II) complexes of N-allyl-N'-(4'-methylthiazol)-2ylthiourea (AllMeTzTu), HL, have been studied by TG, DTG, and DTA curves. The complexes have the molecular formulae as CoL3.H2O, [Cu(HL)Cl2]0.5H2O and [CuL2(H2O)2] a square for ML2 (M = NiII, PdII and PtII), and [Pd(HL)Cl2]. The TG curves show that the four-coordinate complexes decompose in two stages to yield a free metal ,with exception [Pd(HL)Cl2] which gives PdS, as a residue, while the two six-coordinate complexes CoL3.H2O, and [CuL2(H2O)2] decompose in three stages to yield Co

Abstract:

The composition and stability of the complexes of isatin-?-thiosemicarbazone with Co(II), Ni(II), Cu(II), Zn(II), Pd(II) and Hg(II) have been investigated using spectrophotometric method at 30?C and constant ionic strength of 0.1 mol dm-3 (KNO3) in 70 % ethanol. Experimental results indicate the formation of MeL and MeL2 complexes for Ni(II) and Co(II), and MeL for Cu(II), Zn(II), Pd(II) and Hg(II) complexes, whose stability constants, ?n, have been calculated using a computerized iterative method of successive approximation.

The phosphine-stabilized azido complexes [M(N3)2(PTA)2] (M = Pd, Pt; PTA = 1,3,5-triaza-7-phosphaadamantane) were prepared in high yields by a ligand exchange reaction from cis-[Pd(N3)2(tmeda)] and cis-[Pt(N3)2(cod)], respectively. The Pd and Pt complexes [M(N3)2(PTA)2] undergo cycloaddition reactions with various isothiocyanates to give complexes containing anionic, S-coordinated tetrazole-thiolate ligands of the type trans-[M(SCN4R)2(PTA)2] (M = Pd, Pt; R = Et, allyl, Me, Ph). The molecular structures of several of these derivatives were determined by X-ray crystallography.Key words: palladi
