cis-(Pyridin-2-ylcarbonimidodithioato-κ²S,S′)bis(triphenylphosphane-κP)palladium(II)

Abstract

Key indicators: single-crystal X-ray study; T = 173 K; mean (C-C) = 0.003 Å; R factor = 0.023; wR factor = 0.055; data-to-parameter ratio = 17.1.The title compound, [Pd(C 6 H 4 N 2 S 2 )(C 18 H 15 P) 2 ], was obtained as a minor product from the reaction of trans-PdCl 2 (PPh 3 ) 2 with piperazine-1,4-dicarbothioic acid bis(pyridin-2-yl)amide. The Pd II atom displays a slightly distorted square-planar PdP 2 S 2 geometry with a bidentately coordinated pyridin-2-ylcarbonimidodithioate ligand and two triphenylphosphine molecules, coordinated in cis positions. The crystal structure features weak -[centroid-centroid distance =3.7327(15) Å ] and C-HÁ Á Á interactions and contains an almost spherically shaped void of 50.4 Å 3 per unit cell.
