A new easily synthetic route with a 96% yield of ligand 2-(3,5-diphenyl-1H-pyrazol-1-yl)ethanol (L) is obtained. The reactivity of L against Pd(II), Zn(II) and Cu(II) leads to [PdCl 2 (L) 2 ] (1), [ZnCl 2 (L)] (2) and [CuCl(L′)] 2 (3) (L′ is the ligand L without alcoholic proton), respectively. According to the different geometries imposed by the metallic centre and...
The stereochemical preferences of copper complexes of 2,6-bis-(3,5-dimethylpyrazol-1-ylmethyl)pyridine (L 1 Me 2 ) and of 2,6-bis-(phenylpyrazol-1-ylmethyl)pyridine (L 1 Ph) have been investigated. The single crystal X-ray structures of [Cu(OH 2 )(L 1 Me 2 )](BF 4 ) 2 and [CuCl(HOMe)(L 1 Me 2 )]BF 4 show near-regular...
