Molecular structure and absolute configuration of a cluster with a bridging dihydroimidazole ligand [Elektronische Daten] [V. Kirin, V. Maksakov, A. Virovets, P. Petukhov, S. Popov, A. Tkachev] Reactions of the triosmium clusters Os3(CO)11(NCMe) (1) and Os3(CO)10(NCMe)2 (2) with terpene derivatives,viz., (1S,3S,4R,6R)-3-(N,N-dimethylamino)-4-amino-3,7,7-trimethylbicyclo [4.1.0]heptane (3). (3bR,4aR)-(3,4,4-trimethyl-3b,4,4a,5-tetrahydrocyclopropa [3,4]cyclopenta[1,2-c]pyrazol-1-yl)acetic acid (4a), and (3bR,4aR)-3-(3,4,4-trimethyl-3b, 4,4a,5-tetrahydrocyclopropa[3,4]cyclopenta[1,2-c]pyrazol-1-yl)propionic acid (4b), were studied. A complex with the terminally coordinated ligand is formed in the first step of the reaction of diamine3 with cluster1. Heating of the resulting complex is accompanied by activation of one of the methyl groups of the ligand to form diastereomers with the bridging tricyclic dihydroimidazole ligand. One of these diastereomers was studied by X-ray diffraction analysis and its absolute configuration was established. Pyrazolycarboxylic acids react with cluster2 as simple organic acids and are coordinated as a bridge at the Os—Os bond through the carboxyl group.
