Bis[1,3-bis­(2,4,6-trimethyl­phen­yl)-2,3-dihydro-1H-imidazol-2-yl­idene]dichloridodinitro­syltungsten(II) tetra­hydro­furan-d 8 monosolvate

By Javier Fraga-Hernández, Olivier Blacque and Heinz Berke


The mol­ecular structure of the title compound, [WCl2(NO)2(C21H24N2)2]·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 Ccarbene—W—Ccarbene bond angle of 173.44 (18)° and the Cl—W—Nnitros­yl bond angles of 171.34 (11) and 171.32 (13)° 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) Å, respectively. An inter­molecular C—H⋯O inter­action connects the organometallic mol­ecule and the tetra­hydro­furan-d 8 solvent mol­ecule
