Photo-chemical isomerism of the cis-[PdII/PtII(L-κS,O)2] complexes of N,N-di-ethyl-N′-3,4,5-trimethoxy-benzoylthiourea (HL) in acetonitrile reversibly produces geometric trans-[PdII/PtII(L-κS,O)2] isomers in solution after irradiation with visibl

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

An array of pincer-like bis(pyrazole)pyridinyl (1–10) and bis(imidazole)pyridinyl compounds (11 and 12) with varying alkyl pendant arms was synthesised and spectroscopically characterised. The classic Knorr approach for the synthesis of pyrazoles w

In recent years, the versatile coordinating nature and facile construction of mixed donor (O, N, S) acyl(aroyl)thiourea ligands has led to the design and synthesis of new photo-active, macrocyclic and heteroleptic complexes. Although a significant po

The reaction of a series of N,N-di-substituted aroylthioureas (HL1−3; L1 = H, L2 = Cl, L3 = OMe) with the Pd(II) centre in K2PdCl4 leads to cis-[Pd(L1−3-κS,O)2] complexes exclusively which then undergoes photo-induced isomerism to the trans-[Pd(

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
