    In the title compound, C22H19NO5S·C2D6OS, the central six-membered ring has a slightly distorted boat conformation, while the fused pyrrolidine ring adopts an envelope conformation. These conformations are stabilized by O—H?O hydrogen bonds between the main compound and solvent molecules. In addition, intramolecular C—H?O hydrogen bonds in the main molecule form two S(6) rings. Molecules are connected by pairs of intermolecular C—H?O hydrogen bonds, forming dimers with a R22(8) motif. These dimers form a three-dimensional network through O—H?O, O—H?S and C—H?O hydrogen bonds with each other directly and through solvent molecules. In addition, weak ?–? stacking interactions [centroid-to-centroid distances = 3.9937?(10) and 3.9936?(10)?Å, slippages of 2.034 and 1.681?Å] are observed. The intermolecular contacts were quantified using Hirshfeld surface analysis and two …

    Crystal structure of [1,3-bis­­(2,4,6-tri­methyl­phen­yl)imidazolidin-2-yl­­idene]di­chlorido­(2-{[(2-methoxyeth­yl)(meth­yl)amino]­meth­yl}benzyl­­idene)ruth­en­ium

    The title compound, [RuCl2(C33H43N3O)], is an example of a new generation of N,N-dialkyl ruthenium catalysts with an N—Ru coordination bond as part of a six-membered chelate ring. The Ru atom has an Addison ? parameter of 0.244, which indicates a geometry intermediate between square-based pyramidal and trigonal–bipyramidal. The complex shows the usual trans arrangement of the two chlorides, with Ru—Cl bond lengths of 2.3515?(8) and 2.379?(7)?Å, and a Cl—Ru—Cl angle of 158.02?(3)°. One of the chlorine atoms and the atoms of the 2-methoxy-N-methyl-N-[(2-methylphenyl)methyl]ethane-1-amine group of the title complex display disorder over two positions in a 0.889?(2): 0.111?(2) ratio.
