Crystal structure of homodinuclear platinum complex containing a metal-metal bond bridged by hydride and phosphide ligands.

In the title compound, µ-di-phenyl-phosphido-µ-hydrido-bis-[bromido-(tri-phenyl-phosphane-κP)platinum(II)] diethyl ether monosolvate, [Pt2Br2(C12H10P)H(C18H15P)2]·C4H10O or [Pt2(µ-H)(µ-PPh2)Br2(PPh3)2]·(C2H5)2O, the PtII atoms are coordinated in a distorted square-planar arrangement, with one hydrido and one phosphido ligand bridging in a trans position. In the lattice, C-H⋯·O and C-H⋯π interactions are present. This complex has a total number of 32 electrons, 16 electrons for each PtII atom. One of the Br atoms is disordered over two positions in a 0.92:0.08 ratio.

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

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.
