Copper(I) halides react with mono- and polychalcogenoethers and -chalcogenones to form 0-3D coordination materials containing neutral polynuclear Cu_xX_xE_y species (E = S, Se, Te; X = Cl, Br, I; x = 2–8) called secondary building units (SBU). These species exhibit two general types of motifs namely globular and quasi-planar. Depending on the shape of these polynuclear species and the dimensionality of the network, their properties and applications are profoundly different. In a structural point of view for instance, when X = I, and E = S, the globular family includes cubane, open cubane, fused dicubane, fused open dicubane, hexagonal prism, and 1D-polycubane. Concurrently, the quasi-planar family includes rhomboid, trinuclear cluster, step staircase, 1D-zig zag ribbon, 1D-acordeon ribbon and 1D-staircase ribbon. Both the cubane and rhomboid motifs are overwhelmingly represented (>80%). Generally, the globular species are generally strongly luminescent. In contrast, the quasi-planar family exhibits only modest intensity luminescence or no emission at all. This review provides a thorough statistical analysis of these SBUs, in a structural point of view, along with their photophysical properties.

铜 (I) 卤化物与单和多硫属元素醚和 - 硫属元素酮反应形成 0-3D 配位材料，其中包含中性多核 Cu _x X _x E _y物种（E = S、Se、Te；X = Cl、Br、I；x = 2-8) 称为二级建筑单元 (SBU)。这些物种表现出两种一般类型的图案，即球状和准平面状。根据这些多核物质的形状和网络的维度，它们的性质和应用有很大的不同。例如，从结构的角度来看，当 X = I 且 E = S 时，球状族包括立方烷、开立方烷、熔融双立方烷、熔融开放双立方烷、六棱柱和一维多立方烷。同时，该准平面族包括菱形、三核簇、阶梯形、一维之字形带、一维手风琴带和一维楼梯带。立方体和菱形图案都占绝大多数（> 80％）。通常，球状物质通常是强发光的。相比之下，准平面族仅表现出中等强度的发光或根本不发光。本综述从结构的角度对这些 SBU 及其光物理特性进行了全面的统计分析。
