Tris(η⁵-cyclo­penta­dien­yl)-tris­[η⁶-[9,10-dihydro­anthracene-9,10-endo-3′,4′-(N-benz­yl)pyrrolidine]]triruthenium(II) tris­(hexa­fluoro­phosphate) acetone disolvate

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).

In the title compound, C₂₅H₂₃N·CHCl₃, the dihydro­anthracene unit is bent with a dihedral angle between the benzene rings of 57.82 (8)°. The N atom of the pyrrolidine heterocycle, which has an envelope conformation with the N atom as the flap, exhibits a pronounced pyramidalization [Σ(C—N—C) = 328.07°], indicating an accentuated N-donor character. In the crystal, this behaviour is evident by the C—H...N hydrogen bond involving a solvent mol­ecule and the N atom. The absolute configuration at the C-atom fused positions of the pyrrolidine group were crystallographically confirmed to be S and R.
