摘要：
The molecular structure of the title compound, [WCl2(NO)(2)-(C21H24N2)(2)]center dot C4D8O, 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 WCl2 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.
