Azido-[1,2-bis-(diphenyl-phosphan-yl)ethane-κP,P'](η-inden-yl)ruthenium(II).

Facile ligand substitution is observed when the ruthenium chloride complex [Ru(η(5)-C(9)H(7))Cl(dppe)] (dppe is diphenylphosphanyl ethane) is treated with NaN(3) in refluxing ethanol, yielding the title compound, [Ru(η(5)-C(9)H(7))(N(3))(dppe)] or [Ru(C(9)H(7))(N(3))(C(26)H(24)P(2))]. The Ru(II) atom has a typical piano-stool coordination. The Ru-P bond lengths are 2.284†(2) and 2.235†(2)†à . NMR and MS analyses are in agreement with the structure of the title compound.
