Abstract
The Schiff-base condensation of 2-(N,N-dimethylcarbamoylthio)-5-methylisophthaldehyde with 2-(2-aminoethyl)pyridine, in the presence of Pd2+, gives the complex [Pd2LCl2]Cl·H2O·0.5CH3OH (1a), where L = 4-methyl-2,6-bis[2-(2-pyridyl)ethyliminomethyl]thiophenolate, and a monopalladium monoaldehyde complex, (2). The structure of (1a) was established by a single-crystal X-ray diffraction study: the crystals are monoclinic, space group Cc, with a= 24.186(4), b= 14.911(2), c= 15.299(2)Å, β= 104.87(1)°; refined to R= 0.026 for 5 067 reflections [I 3σ(I)] collected by counter methods. The structure of [Pd2LCl2]+ reveals two chloride ions at the exogenous bridging site of the complex, one bound to each palladium. Spectroscopy suggests an analogous structure for [Pd2L(CH3CO2)2]PF6.Keywords
