Crystal structure of (µ-N,N'-di-benzyl-dithio-oxamidato-κN,S:N',S')bis-[(η(3)-crotyl)palladium(II)].

ABSTRACT

In the centrosymmetric dinuclear title compound, [Pd2(C4H7)2(C16H14N2S2)], the metal atom is η(3)-coordinated by three C atoms of a crotyl ligand [Pd-C = 2.147 (4), 2.079 (5) and 2.098 (5) Å], the longest distance influenced by the steric inter-action with the benzyl substituents of the di-benzyl-dithio-oximidate (DTO) ligand. The Pd-N and Pd-S bonds to this ligand are 2.080 (3) and 2.3148 (9) Å, respectively, completing a square-planar coordination environment for Pd(II). The benzyl groups are oriented so as to maximize the inter-action between a benzylic H atom and an S atom, resulting in a dihedral angle of 77.1 (2)° between the benzene rings and the metal complex plane. In the crystal, no inter-complex hydrogen-bonding inter-actions are present.
