Facile ligand substitution is observed when the ruthenium chloride complex [Ru(η(5)-C(9)H(7))Cl(PPh(3))(2)] is treated with 1,4-bis-(diphenyl-phosphan-yl)butane in refluxing toluene yielding the title compound, [Ru(C(9)H(7))Cl(C(28)H(28)P(2))]. The Ru(II) atom has a typical piano-stool coordination, defined by the indenyl ligand, one Cl atom and two phosphanyl P atoms. The Ru-P bond lengths are 2.2502 (9) and 2.2968 (8) Å.
