Preparation and Crystal Structure of Binuclear Chloro{6-[[Chloro(triphenylphosphine)platinum](Mesitylimino)methyl]pyridin

Abstract

Treatment of N,N′-bis(mesityl)pyridine-2,6-carboxyimidoyl dichloride, 1, in toluene solution with [Pt(PPh<inf>3</inf>)<inf>4</inf>] at 100 °C afforded a novel platinacyclic compound, 3, in 63% yield, instead of the expected compound 2. The molecular and crystal structures of the title compound, 3, have been determined by the single crystal X-ray diffraction technique. The coordination geometries around the Pt atoms are distorted square-planar. In the crystal structure, the molecules are linked by a pair of C-H···N hydrogen bonds into a centrosymmetric dimer with an R<inf>2</inf>2 (16) ring, centred at (1/2,1/2,1/2). © 2008 Elsevier Ltd.
