Crystal and molecular structure of di-µ-acetato-bis-[(2-methylallyl-3-norbornyl)palladium(II)]

Abstract

A three-dimensional structure analysis of the title compound has been carried out from diffractometer data by Patterson and Fourier methods. Crystals are orthorhombic, with a= 11·822, b= 12·513, c= 17·609 Å, space group Pbcn, Z= 8. The structure was refined by least squares to a final R of 0·062 for 2215 observed reflections. The molecule is dimeric, symmetry C₂, with a Pd ⋯ Pd distance of 2·960(1)Å. The co-ordination geometry about each Pd ion is approximately square-pyramidal, with the vinyl end of the lateral chain of the hydrocarbon ligand being shifted from the ‘normal’ position in related Pd and Pt complexes. The Pd–O distances show evidence of trans-influence by the co-ordinated carbon atom of the norbornyl moiety.
