N2  - The crystal and molecular structure of the 1-propylimidazolate bridged binuclear complex, LPd2(primid) has been determined by single-crystal X-ray diffraction techniques at 20ºC; disordered ethanol molecules are also present in the lattice. The quinquedentate ligand L3- is formally the trianion &#945;,&#945;'-{(2-mercapto-4-methylbenzene-1,3-diyl)di(methylidyne)di(azino)bis(cyclohexane-methanol)ato(3 -). Crystals of LPd2 (primid) are triclinic, P1, with a 7.078(2), b l3.615(3), c 17365(3) Å, &#945; 78.52(2), &#946; 80.21(2) and &#947; 83.83(2)º. The structure was solved by conventional Fourier methods and refined by full-matrix least-squares procedures to convergence with R and Rw 0.053 obtained for the 4133 statistically significant structure amplitudes. The ligand sidearms are essentially equivalent with both palladium centres displaying similar distorted square-planar geometries, the separation being 3.605 Å. The propylimidazolate bridging group is comfortably accommodated within the binuclear framework and displays a geometry typical of metal complexes of imidazole and its derivatives. Coordination to the palladium centres occurs through C4 and N3, a bridging mode not previously characterized by X-ray crystallography, and one which illustrates the remarkable stability and flexibility of the binuclear LPd2+ core.
