摘要
通过化学气相传输反应首次获得了硒铜镉溴化物 Cd7Cu2(SeO3)8Br2 (1)。新化合物呈三菱形，P 1 ‾ $P\overline{1}$ , a = 5.3280(5) Å, b = 10.6190(12) Å, c = 11.4380(13) Å, α = 100.856(4)°, β = 93.321(4)°, γ = 91.021(4)°, V = 634.22(12) Å3, R 1 = 0.027。1 在结构上没有类似物，属于一种新的结构类型。1 的结构可以描述为一种主客体结构。宿主是[Cd7(SeO3)8]2-间断框架，由具有大孔径的之字形层组成。客体是溴化铜。因此，其结构式可写成 [Cd7(SeO3)8]{Cu2Br2} 。
[Cd7(SeO3)8]{Cu2Br2}, a host-guest structure derived from β-CdSeO3
A first cadmium copper selenite–bromide Cd7Cu2(SeO3)8Br2 (1) was obtained via chemical vapor transport reactions. The new compound is triclinic, P1‾$P\overline{1}$, a = 5.3280(5) Å, b = 10.6190(12) Å, c = 11.4380(13) Å, α = 100.856(4)°, β = 93.321(4)°, γ = 91.021(4)°, V = 634.22(12) Å3, R1 = 0.027. 1 has no structural analogs and belongs to a new structure type. The structure of 1 can be described as a host-guest architecture. The host is the [Cd7(SeO3)8]2− interrupted framework, which consists of zigzag layers with a large aperture. The guests are copper bromide species. Thus, the formula can be written as [Cd7(SeO3)8]{Cu2Br2}.
