Cis-Dichlorido[4,4,5,5-tetra-methyl-2-(2-pyrid-yl)-2-imidazoline-1-ox-yl]-palladium(II) tetra-hydro-furan hemi-solvate.

ABSTRACT: The asymmetric unit of the title complex, [PdCl(2)(C(12)H(16)N(3)O)]·0.5C(4)H(8)O, consists of one palladium complex in a general position and one half tetra-hydro-furan (THF) solvent mol-ecule, with the O atom lying on a twofold rotation axis. The Pd(II) atom is bound to one chelating imino nitroxide radical through two N atoms, one from the pyridyl ring and the other from the imidazoline ring. The coordination of the metal centre is completed by two Cl atoms in a cis configuration, leading to a quasi-square-planar coordination of the metal centre. The four atoms that define the Pd(II) coordination environment and the eight atoms that belong to the pyridylimine fragment are coplanar, with no deviation larger than 0.087?(5)?Å. In the crystal structure, inter-molecular inter-actions shorter than the corresponding van der Waals radii sum are observed only between Pd(II) complexes, and no short contact is observed around the THF mol-ecule. Weak C-H?O and C-H?Cl inter-actions yield a two-dimensional network of complexes in the (101) plane.
