Abstract
The coordination ability of Ag2[B12Cl12] in the presence of S-containing ligands (tetrahydrothiophene, tetramethylthiourea, 1,3-diisopropyl-2-thiourea, 1,3-dithiole-2-thione) was studied. Mononuclear silver(I) complexes [Ag(L1)4]2[B12Cl12] (L1 is tetrahydrothiophene) and [Ag(L2)3]2[B12Cl12] (L2 is tetramethylthiourea) as well as binuclear silver(I) complexes [Ag2(Lx)6][B12Cl12] (x = 3, 4; L3 is 1,3-diisopropyl-2-thiourea, L4 = 1,3-dithiole-2-thione) were isolated and studied by NMR, IR spectroscopy and single-crystal X-ray diffraction. In all complexes isolated, the perhalogenated boron cluster [B12Cl12]2– plays the role of a counterion.
