Abstract

A series of new neutral and cationic palladium(II) complexes of type [Pd(L-L)X₂] (5, 6, 9, 10), [Pd(L-L)Y₂](BF₄)₂ (7, 8, 11, 12) and [Pd(η³-C₆H₉)(L-L)](PF₆) (13, 14), (L-L = 1,2-bis(N-indolinyl)ethane (BIE, 3), 1,2-bis(N-1,2,3,4-tetrahydroquinolinyl)ethane (BTQE, 4); X = Cl, NO₃; Y = MeCN, H₂O) have been prepared and characterized. These investigations show that BIE and BTQE can lead to chiral C₂-symmetric complexes, as well as to the achiral meso compounds. A nearly quantitative yield of the C₂-symmetric isomer was found for the reaction of (PhCN)₂PdCl₂ with BIE and BTQE. The solid state structures of the C₂-symmetric [Pd(BIE)Cl₂] (5a) and the meso isomer of [Pd(η³-C₆H₉)(BIE)](PF₆) (13b) have been determined by X-ray structure analysis.
