trans-Bis[bis(diphenylphosphino)methane-κ²P,P′]dichlororuthenium(II) dichloromethane disolvate acetone hemisolvate hemihydrate

Abstract

The title compound, [RuCl2(C25H22P2)2]·2CH2Cl2·0.5C3H6O·0.5H2O, was obtained as unreacted starting material from our attempts to prepare acetyl­ide complexes of ruthenium, based on 1,4‐dieth­oxy‐2,5‐diethynylbenzene bridging ligands, in a route towards mol­ecular wires. The complex is centrosymmetric.

trans-Bis[bis(diphenylphosphanyl)methane-κ2 P,P′]dichloridoruthenium(II): a triclinic polymorph

“…The title compound was reported previously, crystallizing as a monoclinic ansolvate (Chakravarty et al, 1984). Moreover, various solvated forms are also known: a triclinic N, N-dimethylformamide solvate (Treigerman & Sasson, 2017), a triclinic dichloromethane acetone solvate hemihydrate (Figueira et al, 2006), and a triclinic dideuterodichloro-methane solvate (Lynam et al, 2008). We report here the triclinic polymorph of the ansolvate.…”

“…1), with the Ru II atoms situated at inversion centers (at 0,0,0 and 1/2, 1/2, 1/2). Bond lengths and angles of the Ru II coordination spheres (Table 1) are within the range of the monoclinic polymorph (Chakravarty et al, 1984) or the solvated triclinic solvates (Treigerman & Sasson, 2017;Figueira et al, 2006;Lynam et al, 2008).
