Özet

The title complex, di-mu-chloro-bis[chloro(eta(6)-p-cymene)ruthenium(II)]-9H-carbazole (1/2), [Ru2Cl4(C10H14)(2)](.)2C(12)H(9)N, is composed of one [RuCl2(eta(6)-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 eta(6) manner; the (RuRu)-Ru-... separation is 3.688 (3) angstrom. The title complex has a crystallographic centre of symmetry located at the mid-point of the (RuRu)-Ru-... line. Intermolecular N-(HCl)-Cl-... and pi-pi 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.
