Secondary interactions, in which decachloro-closo-decaborate anions are involved were studied in solvates [Fe(phen)3][B10Cl10]·0.875CH3CN·0.125H2O (1), {[Fe(bipy)3][B10Cl10]}·2Bipy·0.5CH3CN (2), {[Fe(bipy)3]2[B10Cl10]2}·2.25CH3CN (3), and [Fe(bipy)3]3[B10Cl10]3·2CH3CN·H2O (4). Structures 1–4 were determined by X-ray diffraction analysis, and complexes 1–3 were studied using 35Cl NQR spectroscopy. A number of C–H···Cl and p···π interactions between chlorine atoms and delocalized electron density of phenyl rings or C≡N groups of acetonitrile molecules were identified. The results obtained by the two methods were compared and the relative strength of secondary interactions were estimated.
