Formation and structural characterization of novel polynuclear palladium selenolato complexes [Pd3Se(SePh)3(PPh3)3]Cl and [Pd6Cl2Se4(SePh)2(PPh3)6]

Chlorido-{2-[(di-methyl-amino)-meth-yl]benzene-seleno-lato-κ(2) N,Se}(tri-phenyl-phosphane-κP)palladium(II)

The asymmetric unit of the title compound, [PdCl(C₉H₁₂NSe)(C₁₈H₁₅P)], contains two independent mol­ecules. In both cases, the Pd²⁺ cations are coordinated by the Se and N atoms of the chelating bidentate 2-[(di­methyl­amino)­meth­yl]benzene­seleno­late ligand. The chloride ligand lies trans to selenium and the tri­phenyl­phosphane ligand is trans to nitro­gen. The Pd—Se bond lengths in the two independent coordination environments of Pd are 2.3801 (4) and 2.3852 (4) Å, the Pd—P bond lengths are 2.2562 (8) and 2.2471 (8) Å, the Pd—N bond lengths are 2.172 (2) and 2.158 (2) Å, and the Pd—Cl bond lengths are 2.3816 (8) and 2.3801 (8) Å. The square-planar coordination around one Pd²⁺ cation is less distorted than that around the other.
