Crystal structures of di-iodido-bis-[(1S,5S)-4-mesityl-1,2,8,8-tetra-methyl-2,4-di-aza-bicyclo-[3.2.1]octan-3-yl-idene-κC (3)]palladium(IV) and di-chlorido-[(1S,5S)-4-mesityl-1,2,8,8-tetra-methyl-2,4-di-aza-bicyclo[3.2.1]octan-3-yl-idene-κC (3)](tri-phenyl-phosphane-κP)palladium(IV).


ABSTRACT: The mol-ecular structures of the chiral title compounds, [Pd(C19H28N2)2I2], (I), and [Pd(C19H28N2)Cl2(C18H15P)], (II), show a distorted square-planar coordination around the Pd(II) atoms with two halogenide (Hal) ligands each and two N-heterocyclic carbene (NHC) ligands in (I) or one NHC and one tri-phenyl-phosphane ligand in (II). The deviations of the Pd(II) atoms from the L 2Hal2 best plane (L = NHC or tri-phenyl-phosphane ligand) are 0.206 (1) Å for (I) and 0.052 (1) Å for (II). The crystal packings exhibit inter-molecular C-H⋯Hal hydrogen bonds.
