Tris(η5-cyclo­penta­dien­yl)-tris­η6-910-dihydro­anthracene-910-endo-3′4′-(N-benz­yl)pyrrolidinetriruthenium(II) tris­(hexa­fluoro­phosphate) acetone disolvate

摘要

In the title compound, [Ru3(C25H23N)(C5H5)3]·3PF6·2C3H6O], the cation is a triruthenium complex of a 9,10-dihydro­anthracene derivative. Three RuCp⁺ (Cp is cyclo­penta­dien­yl) groups are bonded to the three aromatic rings of the ligand. Surprisingly, the pyramidalized N atom of the heterocycle (Σ C—N—C = 329.0°) points towards the anthracenyl group, so losing its coordinative ability. There is an inter­molecular C—H⋯π inter­action involving an acetone mol­ecule and the adjacent benzyl ring of the ligand. In the crystal, mol­ecules are linked via a number of C—H⋯O and C—H⋯F inter­actions and a C—H⋯π inter­action, leading to the formation of a three-dimensional supra­molecular structure. One of the Cp groups is disordered over two positions, with refined occupancies of 0.695 (14):0.305 (14). Two of the three hexa­fluoro­phospate anions are disordered, with refined occupancies of 0.630 (6):0.370 (6) and 0.771 (8):0.229 (8). One of the two solvent acetone mol­ecules is also disordered, with refined occupancies of 0.82 (2):0.18 (2).
