Öğe Crystal structure of [RuCl2[N-(2,4,6-trimethyl-benzyl)N-(n-butyl)]-imidazolidin-2-ylidene] and [RuCl2[N-(2,4,6-trimethyl-benzyl)-N-(2-methoxyethyl)]imidazolidin-2-ylidene](Springer/Plenum Publishers, 2005) Arslan, H; VanDerveer, D; Ozdemir, I; Cetinkaya, B; Demir, STwo 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.Öğe Crystal structure of dichlorido(N-(biphenyl-2-ylmethyl)-N-(2-ethoxy-ethyl)]-imidazolidin-2-ylidene(?6-hexamethylbenzene)ruthenium, Ru(C12H18)(C20H24N2O)Cl2(R Oldenbourg Verlag, 2004) Arslan, H; Vanderveer, D; Özdemir, I; Cetinkaya, B; Yasar, SC32H42Cl2N2ORu, monoclinic, P12(1)/cl (no. 14), a = 12.930(4) Angstrom, b = 18.094(6) Angstrom, c = 13.655(4) Angstrom, beta = 114.00(2)degrees, V = 2918.4 Angstrom(3), Z = 4, R-gt(F) = 0.046, wR(ref)(F-2) = 0.133, T = 193 K.Öğe Crystal structure of dichloro-N-(3,4,5-trimethoxy-benzyl)-N-(n-butyl)]imidazolidin-2-ylideneruthenium(II), RuCl2(C17H26N2O3)(R Oldenbourg Verlag, 2004) Arslan, H; Vanderveer, D; Özdemir, I; Cetinkaya, B; Demir, SC17H26Cl2N2O3Ru, monoclinic, P12(1)/nl (no. 14), a = 10.180(1) A, b = 11.985(1) A, c = 16.017(2) A, beta = 106.419(2)degrees, V = 1874.5 A(3), Z = 4, R-gt(F) = 0.037, wR(ref)(F-2) = 0.109, T = 193 K.Öğe Dichloro[3-(1-naphthylmethyl)-1-(2,4,6-trimethylbenzyl)imidazolidin-2-ylidene]ruthenium(Blackwell Publishing, 2005) Arslan, H; VanDerveer, D; Özdemir, I; Yasar, S; Çetinkaya, BIn the title compound, [RuCl2(C24H26N2)], the multidentate ligand functions as both an arene and a carbene, and occupies four coordination sites. The two Cl atoms complete a distorted octahedron about the Ru atom.
