Abstract—Silver(I) complex formation with closo-dodecaborate anion was studied systematically in various
media: water, acetonitrile, and acetonitrile/trifluoroacetic acid (TFA). A possibility of formation of complexes
Cat[AgB₁₂H₁₂] and [Ag₂B₁₂H₁₂] was demonstrated. Synthesis parameters (reaction medium, reagent ratio, and
cation size in precursor dodecaborate) were shown to affect the type of the resulting complex and the coordi-
nation sphere around the central atom.
