Crystal structure of azido-(?(5)-cyclo-penta-dien-yl)bis-(tri-phenyl-phosphane-?P)ruthenium(II) di-chloro-methane hemisolvate.

ABSTRACT: The title solvated complex, [Ru(?(5)-C5H5)(N3){P(C6H5)3}2]·0.5CH2Cl2, displays a typical piano-stool geometry about the Ru(II) atom. The bond lengths and angles of the cyclo-penta-dienyl and phosphane ligands are very similar to that of the unsolvated complex [Taqui Khan et al. (1994 ?). Acta Cryst. C50, 502-504]. The azide anion displays similar N-N distances of 1.173?(3) and 1.156?(3)?Å and has an N-N-Ru angle of 119.20?(15)°, indicating a greater contribution of the canonical form Ru-N=N((+))=N((-)) for the bonding situation. An intra-molecular C-H?N hydrogen-bonding inter-action between one ortho H atom of a phosphane ligand and the N atom coordinating to the metal is observed. A similar inter-molecular inter-action is observed between a meta H atom of a phosphane ligand and the terminal azide N atom of a neighbouring complex. Finally, two C-H?N inter-actions exists between the H atoms of the di-chloro-methane solvent mol-ecule and the terminal N atom of two azide anions. The solvent mol-ecule is located about a twofold rotation axis and shows disorder of the Cl atoms with an occupancy ratio of 0.62?(3):0.38?(3).
