One novel 2-D polythreading framework named as [Cu{sub 3}(CN){sub 3}(NH{sub 3})] (1), was obtained through the self-assembling of CuCN under hydrothermal reaction. It is remarkable that there is a 26-membered [Cu{sub 10}(CN){sub 8}] decanuclear metallamacrocycle with the effective size of ca. 16.8x6.83 A{sup 2} along the a-axis. These 2-D layers stack in an ..ABAB...staggered fashion, with the lateral {l_brace}(CN)Cu{sub 3}(NH{sub 3}){r_brace} moieties of each layer inserting into the voids of the decanuclear metallamacrocycles from two adjacent layers. Optical diffuse reflectance spectrum and the result of DFT calculation reveal that 1 is potential direct semiconducting material. In the solid state at room temperature, 1 shows bright yellow fluorescence under ultraviolet light illumination. Its emissive excited state is primarily attributed to the LMCT, LLCT and {sup 3}[MMLCT] excited state, based on the result of DFPT calculation. - Graphical abstract: One novel 2-D polythreading framework [Cu{sub 3}(CN){sub 3}(NH{sub 3})] (1) obtained through the self-assembling of CuCN under hydrothermal reaction shows bright yellow fluorescence at room temperature.
