(η(4)-Tri-methyl-ene-methane)(1,1,1-tris-{[bis-(4-meth-oxy-phen-yl)phosphan-yl]meth-yl}ethane)ruthenium(II) diethyl ether hemisolvate.

The title compound, [Ru(C(47)H(51)O(6)P(3))(C(4)H(6))]·0.5C(4)H(10)O, consists of an Ru(II) atom coordinated by 1,1,1-tris-{[bis-(4-meth-oxy-phen-yl)phosphan-yl]meth-yl}ethane in κ(3)-coordination mode and an η(4)-coordinating tri-methyl-ene-methane ligand. The complex mol-ecule is co-crystallized with a diethyl ether solvent mol-ecule. A half diethyl ether mol-ecule was considered, whereas additional disordered solvent mol-ecules were removed from the diffraction data with the SQUEEZE procedure in PLATON [Spek (2015 ▸). Acta Cryst. C71, 9-18].
