Reaction of CuBr2 with TabHPF6/Et3N in methanol followed by dissolving the resulting precipitate in hydrobromic acid yielded purple blocks of the title complex [Tab-Tab][CuBr4] 1 (C18H26CuBr4N2S2). 1 crystallizes in the monoclinic system, space group P21/n with a = 9.686(3), b = 19.257(5), c = 13.399(4) , = 93.610(9)o, V = 2494.2(13) 3, Z = 4, Dc = 1.911 g/cm3, T = 193(2) K, Mr = 717.71, F(000) = 1396, μ = 74.58 cm-1, S = 1.126, R = 0.0748 and wR = 0.1736 for 2921 observed reflections with I > 2σ(I). The structure of 1 contains a discrete [CuBr4]2- dianion and a [Tab-Tab]2+ dication. In the dianion, the Cu atom is coordinated to four Br atoms forming a distorted tetrahedral coordination geometry. The bromides of the dianion interact with the H atoms of the phenyl and methyl groups of the dications to form a 1D hydrogen-bonded chain.
