(1,3-Dimethylimidazolinylidene)(1-methylimidazolinylidene) gold(I) trifluoromethanesulfonate

The crystal structure of the title compound consists of cationic [Au(C 4 H 6 N 2 )(C 5 H 8 N 2 )] + units with CF 3 SO 3 - counterions. Each Au I centre approaches linear coordination with the two differing imidazolinylidene ligands [C-Au-C 179.0(6)°]. These two essentially planar ligands are almost coplanar having a dihedral angle of 2.54 (4)° between their planes.
