Crystal structure of bis(benzo[h]quinolin-10-yl-C10,N)dicarbonylruthenium(II)

Abstract

The crystal structure of the cis isomer of the title compound, cis-[Ru(CO)₂(bquin)₂](bquin = benzo[h]quinolin-10-yl), has been established at 295 K by single-crystal X-ray diffraction methods, and refined by least squares to a residual of 0.037 for 1 242 independent ‘observed’ reflections. Crystals are monoclinic, space group Pn, with a= 13.682(4), b= 10.885(3), c= 7.497(2)Å, β= 104.05(2)°, and Z= 2. the two carbonyl groups [Ru–C 1.87(1) and 1.81(1)Å] lie trans to the two ligand nitrogen atoms [Ru–N 2.15(1) and 2.16(1)Å]; Ru–C(ligand) are 2.13(1) and 2.12(1)Å.
