摘要
A new selenidomercurate compound, namely(bmmim)2Hg(Se4)2(1, bmmim = 1-butyl-2,3-dimethylimidazolium), has been ionothermally synthesized by the reaction of HgSe, Sb and Se in a mixed solvent of the ionic liquid of(bmmim)Cl and methylamine aqueous solution. The(bmmim)Cl acted as an efficient structure-directing agent(SDA) and reactive solvent in the formation of 1. Single-crystal X-ray diffraction study reveals that 1 crystallizes in the monoclinic space group C2/c with a = 17.9540(10), b = 10.8863(5), c = 16.4728(9)?, β = 110.024(2)°, V = 3025.0(3) ?3, Z = 4, D-1 c = 2.500 mg·m-3, F(000) = 2088, μ = 14.729 mm, R = 0.0186 and wR = 0.0503(I > 2σ(I)). The structure of compound 1 features a bamboo dragonfly-like anion unit of [Hg(Se4)2]2-in which the Hg atom binds to two(Se4)2-groups to form two five-membered rings. The thermal stability and optical property of compound 1 were also investigated.
