Crystal and molecular structure of cis-dichlorobis[methylamino(methoxy)carbene]palladium(II)

Abstract

The title compound has been synthesized and its X-ray structure determined. The structure was solved from diffractometer data by Patterson and Fourier methods and refined by least-squares techniques to R 4.7% for 1 947 independent reflections. Crystals are triclinic, space group P, with unit-cell dimensions: a= 8.45(1), b= 8.26(1), c= 9.19(1)Å, α= 84.8(1), β= 105.2(1), γ= 106.7(1)°, Z= 2. Co-ordination around palladium is square planar and involves two carbene carbons [Pd–C(1) 1.953(8), Pd–C(4) 1.972(10)Å] and two chlorine atoms [Pd–Cl(1) 2.359(4), Pd–Cl(2) 2.390(4)Å]. C–N Distances in the carbene ligands are l.32(1) and 1.29(1)Å, and C–O distances 1.32(1) and 1.34(1)Å.
