Synthesis and crystal structure of [1,3-N,N-bis{2,6-diisopropylphenyl}imidazol-2-ylidene]chloro-[N,N-dimethylbenzylamine-2-C,N]palladium(II)

The title compound 1 has been synthesized and its structure has been determined by singlecrystal X-ray methods. Crystal data: C36H48ClN3Pd, M = 664.62, monoclinic, space group P2(1)/ n with a = 11.857(5), b = 21.042(8), c = 14.632(6) angstrom, beta = 106.492(5), Z = 4, V = 3501(2) angstrom(3), D-c = 1.261 g cm(-3), mu(Mo-K alpha) = 0.633mm(-1), F(000) = 1392; final R and wR = 0.0412 and 0.0889, respectively, for 3265 observed reflections with I >= 2 sigma(I). The Pd(II) atom has distorted square planar geometry, due to the bulk of the isopropyl groups on the NHC ligand. Positioning of the carbenic carbon trans to the amino group and the metalated carbon trans to chlorine is consist with the trans influence
