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

Abstract

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).
