Abstract
The reactivity of sulfonyl-substituted closo-decaborate derivatives (the [2-B10H9SH]2– and [2-B10H9S(CН2C(О)NН2)2]– anions) in the complexation of Ag(I) and Pb(II), Pearson soft acids, in the presence of competitive organic ligands has been studied. The substituted derivatives act as bridging ligands to form silver(I) binuclear complexes [(Ag(bipy)2)2(2-B10H9SH)] and [(Ag(bipy)2)2(2-B10H9S(CН2C(О)NН2)2]NO3; the [2-B10H9SH]2– anion is involved in the lead(II) coordination polyhedron in the [Pb(2-B10H9SH)] and [Pb(bipy)2(2-B10H9SH)] complexes; in [Pb(bipy)2][2-B10H9S(CН2C(О)NН2)2]2, the substituted decaborate derivative acts as a counterion. The solubility of the mixed-ligand complexes is different due to the variety of their structures. The synthesized complexes are the first water-soluble lead and silver compounds with the closo-decaborate anion.
