Dimerization of the 2-(Methylselenomethyl)benzimidazole-silver(I) Cation Involving a AgI-AgI Interaction

Reacting the bidentate ligand 2‐(methylselenomethyl)‐1H‐benzimidazole (msb) with AgBF4 in CH3CN did not produce the expected [Ag(msb)2]+ ion with two five‐membered chelate rings but the dimeric [Ag2(msb)2]2+, isolated and crystallized from acetonitrile/methanol as {[Ag(msb)(CH3CN)]2}(BF4)2 with six‐...

Summary:Reacting the bidentate ligand 2‐(methylselenomethyl)‐1H‐benzimidazole (msb) with AgBF4 in CH3CN did not produce the expected [Ag(msb)2]+ ion with two five‐membered chelate rings but the dimeric [Ag2(msb)2]2+, isolated and crystallized from acetonitrile/methanol as {[Ag(msb)(CH3CN)]2}(BF4)2 with six‐membered chelate rings Ag‐Ag‐Se‐C‐C‐N involving a Ag‐Ag bond of 3.156(1) Å distance. DFT calculations reproduce the observed molecular structure of the dication.
