Copper(I) halides react with sulfides, selenides, and tellurides to form coordination materials containing neutral polynuclear species, which exhibit globular and quasi-planar motifs with different properties and applications.
Copper(I) halides react with mono- and polychalcogenoethers and -chalcogenones to form 0-3D coordination materials containing neutral polynuclear CuxXxEy 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. (C) 2021 Elsevier B.V. All rights reserved.
