Crystal structures of the gold NHC complex bis­(4-bromo-1,3-di­ethyl­imidazol-2-yl­idene)gold(I) iodide and its 1:1 adduct with trans-bis­(4-bromo-1,3-diethyl-imidazol-2-yl­idene)di­iodido­gold(III) iodide

The first title compound, [Au(C(7)H(11)BrN(2))(2)]I, crystallizes in the space group P [Image: see text] without imposed symmetry. The cations and anions are linked to form chains by Br⋯I⋯Br halogen-bond linkages. The second title compound, [Au(C(7)H(11)BrN(2))(2)][AuI(2)(C(7)H(11)BrN(2))(2)]I(2), i...

Sumario:The first title compound, [Au(C(7)H(11)BrN(2))(2)]I, crystallizes in the space group P [Image: see text] without imposed symmetry. The cations and anions are linked to form chains by Br⋯I⋯Br halogen-bond linkages. The second title compound, [Au(C(7)H(11)BrN(2))(2)][AuI(2)(C(7)H(11)BrN(2))(2)]I(2), is an adduct of the first and its formally I(2)-oxidized Au(III) analogue. It also crystallizes in space group P [Image: see text] , whereby both gold atoms occupy inversion centres. The extended structure is a reticular layer involving Br⋯I⋯Br and I⋯I⋯Au linkages.
