The palladium complex prepared from an asymmetrically di-substituted N,N-methyl-ethyl-N′-benzoylthiourea ligand exists in chloroform as a pure mixture of the configurational isomers cis-ZZ-[Pd(L-κS,O)2], cis-EE-[Pd(L-κS,O)2] and cis-ZE-[Pd(L-κS,

Upon ex situ UV-visible light irradiation, complex cis-bis(N,N-diethyl-N′-naphthoylthioureato)-palladium(II), cis-[Pd(L-κS,O)2], undergoes isomerization in acetonitrile-d3 and chloroform-d to yield trans-[Pd(L-κS,O)2] which then rearranges therma

Photo-induced isomerization of cis-[Pd(L1,2-κS,O)2] (HL1 = N,N-diethyl-N′-4-methyl-benzoylthiourea, HL2 = N,N-dimethyl-N′-benzoylthiourea) in acetonitrile solution leads to the reproducible and clean isomerization of rare, new trans-[Pd(L1,2-κS

Photo-irradiation of the cis-[Pd(L1-4-κS,O)2] complexes with visible light leads to formation of trans-[Pd(L1-4-κS,O)2] isomers in acetonitrile, as determined by reverse-phase HPLC (RP-HPLC). In the absence of light, the trans-[Pd(L1-4-κS,O)2] iso

A series of cis-[Pt(L-κS,O)2] complexes derived from the asymmetrically substituted N,N-dialkyl-N’-acyl(aroyl)thiourea ligands HL1-5 have been synthesized and characterized by 1H, 13C, HMBC and 1D NOESY NMR spectroscopy. The complexes exist in chl

The Os(VIII) oxo/hydroxido complexes that are abundant in mild to relatively concentrated basic aqueous solutions are Os(VIII)O4, [Os(VIII)O4(OH)](-) and two cis-[Os(VIII)O4(OH)2](2-) species. Os(VIII) complexes that contain water ligands are thermod

The relative nucleophilic reaction constants npt, for a series of N-(n-propyl)-N′-(para-R-benzoyl)thioureas (R=H, CH3O, (CH3)3C, Br, Cl, C7H15O, I, NO2) have been determined for the substrate trans-[PtCl2(pyridine)2] in methanol–water (75:25 v/v

Recent developments in the fundamental co-ordination chemistry of N-alkyl-N′- (H2L) and N,N-alkyl-N′-acyl(aroyl)thioureas (HL) of Pt(II), Pd(II) and Rh(III) are reviewed. These studies show that the mode of co-ordination of H2L differs markedly f

Oxidation of tetrachloroplatinate(II) by hydrogen peroxide in hydrochloric acid was studied by UV-Vis spectrophotometry. Oxidation takes place via two parallel reactions with hypochlorous acid and hydrogen peroxide, respectively, according to the ove
