Abstract	A novel coordination polymer with the chemical formula $[Cu_{4}Br(CN)(mtz)_{2}]_{n}$ (mtz = 5-methyl tetrazole) (1), has been synthesized under solvothermal conditions and characterized by elemental analysis, infrared (IR) spectroscopy, thermal gravimetric analysis, powder X-ray diffraction and single-crystal X-ray diffraction. Interestingly, the Cu(I), $CN^{−}$ and $mtz^{−}$ in compound 1 are all generated from an in situ translation of the original precursors: $Cu^{2+},$ acetonitrile and 1-methyl-5-mercapto-1,2,3,4-tetrazole (Hmnt). The in situ ring-to-ring conversion of Hmnt into $mtz^{−}$ was found for the first time. Structural analysis reveals that compound 1 is a novel 3D tetrazole-based Cu(I) coordination polymer, containing both metal halide cluster $Cu_{6}Br_{2}$ and metal pseudohalide cluster $Cu_{2}(CN)_{2}$ secondary building units (SBUs), which shows an unprecedented (3,6,10)-connected topology. Notably, a pseudo-porphyrin structure with 16-membered rings constructed by four $mtz^{−}$ anions and four copper(I) ions was observed in compound 1. The fluorescence properties of compound 1 were investigated in the solid state and in various solvent emulsions, the results show that compound 1 is a highly sensitive naked-eye colorimetric sensor for NB and 2-NT (NB = nitrobenzene and 2-NT = 2-nitrotoluene).
