[1,1'-Bis(diphenyl-phosphan-yl)ferrocene-κ(2)P,P'](η(5)-cyclo-penta-dien-yl)(dicyanamido-κN)ruthenium(II) dichloro-methane monosolvate.

ABSTRACT: The title compound, [FeRu(C(5)H(5))(C(2)N(3))(C(17)H(14)P)(2)], was obtained by reaction of Cp(dppf)RuCl [dppf = 1,1'-bis-(diphenyl-phosphan-yl)ferrocene] with sodium dicyanamide in dichloro-methane. The Ru(II) atom is capped by an η(5)-cyclo-penta-dienyl (Cp) ring, a chelating dppf and a terminal C(2)N(3) unit, giving three-legged piano-stool geometry. The C-N-C angle of the N(CN)(2) ligand [120.8 (6)°] is significantly smaller than that in the corresponding diruthenium complex [127.2 (9)°; Zhang et al. (2003 ▶). Inorg. Chem.42, 633-640] due to steric hindrance between the two {Cp(PPh(3))(2)Ru} building blocks. Disorder was found in the dichloro-methane solvent mol-ecule, which was refined as disordered over two positions, with a site-occupancy ratio of 0.53:0.47 (2).
