✦ Synopsis

The title structure, [Ru 2 (C 10 H 15 ) 2 (NO) 2 ], consists of the two Ru atoms doubly bridged via the N atoms of the two NO groups, with two pentamethylcyclopentadienyl (Cp*) rings protruding away from the bridged system on opposite sides. The asymmetric unit contains two independent dimer molecules with an average Ru-Ru distance of 2.538 (7) A ˚and an average Ru-N-Ru angle of 97.2 (3) . The compound was obtained as the product of a facile reaction between Cp*Ru(NO)(OSO 2 CF 3 ) 2 and excess neat 2-propanol. The crystals were grown from CH 2 Cl 2 solution at ambient temperature under a nitrogen atmosphere.

The title dinuclear complex, [Ru 2 (C 10 H 14 )Cl 4 H], has twofold symmetry. The terminal Cl atom interacts with three CÐH H atoms of symmetry-related neighbouring molecules. These interactions play a key role in the packing arrangement.
