2-Bromo-1,3-diisopropyl-4,5-dimethyl-1H-imidazol-3-ium dicyanidoargentate.

ABSTRACT: The title structure, (C(11)H(20)BrN(2))[Ag(CN)(2))], is built up from an approximately C(2v)-symmetric imidazolium cation and a nearly linear dicyanidoargentate anion [N-Ag-N = 176.6?(9)° and Ag-C-N = 178.8?(9) and 177.2?(11)°]. These two constituents are linked by a remarkably short inter-action between the Br atom of the imidazolium cation [C-Br = 1.85?(3)?Å] and one N atom of the cyanidoargentate anion [Br?N = 2.96?(2)?Å], which is much less than the sum of the van der Waals radii (3.40?Å). The crystal studied was twinned by merohedry.

The title structure, (C(11)H(20)BrN(2))[Ag(CN)(2))], is built up from an approximately C(2v)-symmetric imidazolium cation and a nearly linear dicyanidoargentate anion [N-Ag-N = 176.6 (9)° and Ag-C-N = 178.8 (9) and 177.2 (11)°]. These two constituents are linked by a remarkably short inter-action between the Br atom of the imidazolium cation [C-Br = 1.85 (3) Å] and one N atom of the cyanidoargentate anion [Br⋯N = 2.96 (2) Å], which is much less than the sum of the van der Waals radii (3.40 Å).
