Abstract: The single crystal X-ray structure of the imidazolidin ruthenium complex, C_{38}H_{46}N_2Cl_2Ru, was determined. The complex is an orthorhombic space group Pbca with a = 17.3586(32) Å, b = 14.4447(27) Å, c = 27.4325(52) Å, and V = 6878.466(4) Å^3 with Z = 8 for D_{calc} = 1.357 g/cm^3. It exhibits the expected 3-legged piano stool geometry. There is one coordination bond of the ruthenium atom with the electrons of the \eta^6-hexamethylbenzene, 2 symmetrical Ru-Cl bonds, and one Ru-C bond involving the imidazole ring. The coordination around the ruthenium atom is 4-fold, which in this is case is pseudo-tetrahedral.
