Crystal structure of a dicationic Pd(II) dimer containing a 2-[(diisopropylphosphanyl)methyl]quinoline-8-thiolate pincer ligand.

A dicationic Pd(II) dimer, bis{2-[(diisopropylphosphanyl)methyl]quinoline-8-thiolato}palladium(II) bis(hexafluoridoantimonate) dichloromethane monosolvate, [Pd(2)(C(32)H(42)N(2)P(2)S(2))](SbF(6))(2)·CH(2)Cl(2), containing a 2-[(diisopropylphos-phanyl)methyl]quinoline-8-thiolate pincer ligand, was isolated and its crystal structure determined. The title compound crystallizes in the ortho-rhom-bic space group Pbca. A dimeric structure is formed by bridging coordination of the S atoms. The geometry of the butterfly-shaped Pd(2)S(2) core is bent, with a hinge angle of 108.0†(1)° and a short Pd⋯Pd distance of 2.8425†(7)†à . These values are the lowest measured compared to ten dicationic dimers with a Pd(2)S(2) core featuring sulfur atoms embedded in a chelating ligand. One of the two hexa-fluorido-anti-monate anions is disordered over two sets of positions with site-occupancy factors of 0.711†(5) and 0.289†(5). The crystal structure is stabilized by many C-H⋯F and C-H⋯π inter-actions, forming a supra-molecular network.
