Abstract: 0CF.((, Anew complex containing Pd-Wbond, PdW(μ-Ph2Ppy)2(μ-CO)(CO)2Cl2 has been prepared and its crystal and molecular structure determined by X-ray diffraction. The molecule crystallized in the monoclinic space group P21/c with a=14. 616(3) Å, b=15. 289(1) Å, c=17. 676 (1) Å, β=97. 29(1)° and Z=4. the final R=0. 081. The palladium atom is d9 five-coordinated and the tungsten atom is d5 seven-coordinated. Both metal atoms possess the formal oxidation state +1. The molecule is chiral and belongs to the C1 point group.
