Triazole complexes platinum

Infrared data have been tabulated for benzotriazole and a wide range of its transition metal complexes or adducts (172). Far infrared spectra have been recorded for copper(II) benzotriazole adducts and bands at 270-320 cm-1 have been assigned to Cu-N vibrations (172). Infrared absorptions at approximately 825, 800, and 775 cm-1 in the spectra of cobalt(III)/4,5-disubstituted triazolate complexes have been attributed to triazolate ring vibrations (109). Infrared data have been reported and assignments made for palladium and platinum thiatriazoline-5-thionate complexes (37) and for the parent thione (127). Vibrational spectroscopy has been employed in an attempt to determine coordination sites for a range of 8-azapurine complexes (108).

For instance, a new bidentate NHC pyrazolate ligand precursor featuring a methylene spacer between the benzimidazol-2-ylidene and the pyrazolate moieties has been used to obtain four new luminescent platinum(ii) complexes along with either phenyl-pyridine or pyridine-triazole luminophores/ ... 

Platinum ( t) (1 = 1/2). The product, chelation of the coordination of diazenecarboxamides functionalised with the l-(2-picolyl)- H-1,2,3-triazole moiety (la-k) to platinum(II), where K2 PtCl4] and cis-[PtCl2(DMSO)2] were used as the platinum sources, with the metal centre through the 1,2,3-triazole N2 and the pyridyl nitrogen atoms under mild reaction conditions, were structurally characterised by Pt, H and NMR spectroscopy. The formation of the platinum complexes 2a-k was monitored using NMR spectroscopy. The complexation with...
