Abstract

The molecular structure of the title compound, WCl(2)(NO)(2)-(C(21)H(24)N(2))(2)]center dot C(4)D(8)O, displays a distorted octahedral arrangement around the W atom with two trans 1,3-bis(2,4,6-trimethylphenyl) imidazol-2-ylidene (IMes) carbene ligands in axial positions. The four equatorial positions are occupied by nitrosyl and chloride ligands, which are trans to each other. The C(carbene)-W-C(carbene) bond angle of 173.44 (18)degrees and the Cl-W-N(nitrosyl) bond angles of 171.34 (11) and 171.32 (13)degrees deviate only slightly from linearity. The distortion comes from the nitrosyl and chloride ligands which are not fully coplanar since the two N atoms deviate from the WCl(2) plane by -0.279 (4) and 0.272 (4) angstrom, respectively. An intermolecular C-H center dot center dot center dot O interaction connects the organometallic molecule and the tetrahydrofuran-d(8) solvent molecule.
