trans-Bis[1,2-bis(diphenylphosphanyl)ethane]chlorido(ethynyl)ruthenium(II)

The molecular structure of the title compound, trans-[Cu(C2H)Cl(C26H24P2)2], consists of an RuII cation, located on an inversion centre, in an octahedral environment defined by two chelating phosphines, one acetylide and one chloride ligand. The –C[triple-bond]CH and the chlorine ligands are disordered over two equivalent positions (0.5 occupancy each). The coordination geometry is distorted octahedral, with the –C[triple-bond]CH fragment and the Cl ligand in trans positions. The four P atoms occupy the equatorial plane of the octahedron and the chloride and acetylide ligands the axial positions.
