Carbonyl-bis-(triphenyl-phosphane-κP)(η(2)-1-vinyl-pyrrolidin-2-one-κO)ruthenium(0).

ABSTRACT: The 1-vinyl-pyrrolidin-2-one ligand in the title compound, [Ru(C(6)H(9)NO)(C(18)H(15)P)(2)(CO)], coordinates to the Ru(0) atom with the olefin double bond and the ketone O atom. The Ru(0) atom adopts a distorted trigonal-bipyramidal coordination geometry, with the C O ligand and the ketone O atom occupying the axial positions. The two triphenyl-phosphane ligands are cis to each other. The olefinic C=C bond is almost coplanar with the Ru(0) atom and the two P atoms (maximum deviation of 0.0516 Å from the mean plane defined by the five constituent atoms). The coordinated C=C bond has a length of 1.449 (3) Å, which is significantly longer than that of a free C=C bond (1.34 Å). There are two C-H⋯π inter-actions involving neighbouring phenyl rings in the mol-ecule. In the crystal, mol-ecules ar
