摘要：

The palladium-carbene complex, trans-[Pd(EtMeIm)(2)Cl-2] was prepared by carbene transfer via the Ag carbene species. The structure was determined by X-ray crystallography. It crystallizes in the monoclinic unit cell of dimensions of a = 8. 0243(9), b = 8.5320(9), c = 11.7473(13) Angstrom, beta = 100.151(2)degrees with space group of P2(1)/n and Z = 2. The palladium atom is tetracoordinated by two chloride ions and two carbon atoms in a square planar geometry.
