Abstract
The title complex, di-μ-chloro-bis[chloro(η6-p-cymene)ruthenium(II)]–9H-carbazole (1/2), [Ru2Cl4(C10H14)2]·2C12H9N, is composed of one [RuCl2(η6-p-cymene)]2 and two 9H-carbazole molecules. There are one-half of a dinuclear complex and one 9H-carbazole molecule per asymmetric unit. In the dinuclear complex, each of the two crystallographically equivalent Ru atoms is in a pseudo-tetrahedral environment, coordinated by a terminal Cl atom, two bridging Cl atoms and the aromatic hydrocarbon, which is linked in a η6 manner; the Ru⋯Ru separation is 3.688 (3) A. The title complex has a crystallographic centre of symmetry located at the mid-point of the Ru⋯Ru line. Intermolecular N—H⋯Cl and π–π stacking interactions are observed. These interactions form a four-pointed star-shaped ring and one-dimensional linear chains of edge-fused rings running parallel to the [100] direction, which stabilize the crystal packing.
