Abstract Three new Cu(I) cluster complexes, viz. [(Cu{sub 4}I{sub 4})(Cu{sub 2}I{sub 2})(dimb){sub 3}]{sub n} (1; dimb=1,4-diimidazol-1-ylbutane), [(Cu{sub 3}I{sub 2})(dimb)(dmtz)]{sub n} (2; dmtz=3,5-dimethyl-1,2,4-triazole), and [Cu{sub 6}(mbt){sub 6}] (3; mbt=2-mercaptobenzothiazole), have been solvothermally synthesized and structurally characterized. In 1, a Cu{sub 4}I{sub 4} cubane core as a 4-connecting node, connects the neighboring nodes either through single dimb or μ{sub 2}-[(Cu{sub 2}I{sub 2})(dimb){sub 2}] linkers, affording an undulated 2D (4,4) net. Parallel interpenetration occurs between the adjacent nets and thus the overall 2D→3D network is formed. Complex 2 is constructed by 2D (4,4) topological plane grid layers of AB stacking. The core, a distorted triangular bipyramidal Cu{sub 3}I{sub 2} cluster, is acted as a 4-connecting node and connected with dimb and μ{sub 3}-dmtz to form the layer. Complex 3 contains a (Cu{sub 6}S{sub 6}) core in discrete paddle-wheel molecule, which serves as a 4-connecting node to link equivalent ones via π···π interaction, forming 2D (4,4) layers. Solid-state luminescence properties and thermogravimetric analyses of 1, 2 and 3 were investigated. - Graphical abstract: Complexes based on Cu(I) clusters possess two-fold 2D→3D parallel interpenetrating (1), triple emissions (2) and near-infrared emission (3). - Highlights: • Complex 1 represents two-fold 2D→3D parallel interpenetrating framework. • Complex 2 shows triple emissions. • Complex 3 displays a quite intense near-infrared (NIR) emission. • These complexes have good thermal stability.
