    Dichloride [1-(2,4,6-trimethylbenzyl)-3-(biphenyl-2-ylmethyl)-imidazolidin-2-ylidine ( ?6 -hexamethylbenzene] ruthenium
    (2006) Arslan, Hakan; Derveer, Donald Van; Özdemir, İsmail; Yaşar, Sedat; Çetinkaya, Bekir
    The single crystal X-ray structure of the imidazolidin ruthenium complex, C38H46N2C2Ru, was determined. The complex is an orthorhombic space group Pbca with a = 17.3586(32) ˚A, b = 14.4447(27) ˚A, c = 27.4325(52) ˚A, and V = 6878.466(4) ˚A3 with Z= 8 for Dcalc= 1.357 g/cm3. It exhibits the expected 3-legged piano stool geometry. There is one coordination bond of the ruthenium atom with the electrons of the ?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.

    Abstract:The single crystal X-ray structure of the imidazolidin ruthenium complex, C38H46N2C2Ru, was determined. The complex is an orthorhombic space group Pbca with a = 17.3586(32) ˚A, b = 14.4447(27) ˚A, c = 27.4325(52) ˚A, and V = 6878.466(4) ˚A3 with Z= 8 for Dcalc= 1.357 g/cm3. It exhibits the expected 3-legged piano stool geometry. There is one coordination bond of the ruthenium atom with the electrons of the η6-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.
