چکیده
The title compound, C(6)Cl(10), cystallizes in a nearly C2-symmetrical gauche conformation. Both trichloro-vinyl groups are nearly planar [Cl-C-C-Cl torsion angles = -178.47 (12) and -179.93 (11)°] and the lengths of their C-Cl bonds increase from the terminal trans and cis C-Cl bonds to the inter-nal bonds. The Cl-C-Cl bond angles of the terminal dichloro-methyl-ene units are compressed to 111.75 (11) and 111.40 (11)°.

A reaction between [(COD)IrCl]2 (COD is cyclo-octa-1,5-diene), HCl and indene failed to provide the hoped for chlorido-indenyliridium dimer, but instead produced the title compound, [IrCl3(CH3CN)(C8H12)], which is an octa-hedral complex of iridium(III) with a chelating cyclo-octa-1,5-diene ligand, three chloride ligands in a fac arrangement, and one aceto-nitrile ligand. Attempts to devise a ra...

In the title complex, [Rh(C(6)H(16)P(2))(2)][RhCl(2)(C(8)H(12))], the asymmetric unit contains two [Rh(dmpe)(2)] [dmpe = 1,2-bis-(dimethyl-phosphino)ethane] half-cations, lying on inversion centers, and an [RhCl(2)(cod)](-) (cod = 1,5-cyclo-octa-diene) anion, wherein Rh is coordinated by two chloride ligands and two olefinic π-bonds of the cyclo-octa-diene ligand. The Rh atoms in the cations an...
