摘要: Abstract Monocycloplatinated complexes [Pt(HLn)(PPh3)] were synthesized using [Pt(dmso)2Cl2], Nʹ-(arylidene)benzohydrazides (H3Ln, arylidene = 1-naphthylidene or 9-phenanthrylidene), NaOAc·3H2O, and PPh3 in 1:1:1:2 mol ratio. The same reagents 2:1:1:2 mol ratio provided the dicycloplatinated [Pt2(μ-Ln)(PPh3)2Cl]. All have been characterized by elemental analysis, X-ray crystallographic spectroscopic measurements. structures reveal that (HLn)2− acts as pincer-like CNO-donor [Pt(HLn)(PPh3)], while dinucleating (Ln)3− behaves pentadentate ligand is to one metal centre CN-donor second (IR, UV–Vis NMR) features of both types are agreement with their corresponding identities.
