Abstract
Reactions of (Et3NH)2[B10Cl10] and organic ligands 2,2'-bipyridyl (Bipy) and 1,10-phenanthroline (Phen) in the acetonitrile–trifluoroacetic acid system have yielded compounds of composition (HL)2[B10Cl10]·3CH3CN (L = Bipy, Phen). The compounds have been characterized by IR spectroscopy, elemental analysis, and X-ray diffraction (CCDC nos. 2224377 and 2224378). It has been shown that in the presence of trifluoroacetic acid, protonation of organic ligands occurs with the formation of bipyridylium and phenanthrolinium salts, which are stabilized by the decachloro-closo-decaborate anion. It has been found that the cations participate in the formation of hydrogen bonds with the solvate molecules of acetonitrile, while only weak C–H…Cl and B–Cl…π interactions are observed for boron cluster anions.
