Özet

Two imidazolidin ruthenium complexes, [RuCl2[N-(2,4,6-trimethyl-benzyl)-N-(n-butyl)]imidazolidin-2-ylidene], 1, and [RuCl2[N-(2,4,6-trimethyl-benzyl)-N-(2-methoxyethyl)]imidazolidin-2-ylidene], 2, have been synthesised and their crystal structures have been determined from single crystal X-ray diffraction data. Compound I is monoclinic, of space group C2/c with a = 18.466(4) angstrom, b = 14.816(3) angstrom, c = 15.413(3) angstrom, beta = 118.067(2)degrees, and V = 3720.9(12) angstrom(3) with Z = 8 for d(calc) = 1.536 g/cm(3). Compound 2 is monoclinic, of space group P2(1)/c with a = 8.1800(5) angstrom, b = 14.344(8) angstrom, c = 14.809(9), beta = 91.604(10)degrees, and V = 1736.7(18) angstrom(3) with Z = 4 for d(calc) = 1.653 g/cm(3). In each complex the ligand functions as an arene and carbene, occupying four coordination sites. The two chlorines in each compound complete a distorted octahedron.
