abstract A new 2D metal-organic coordination polymer [Cu(trtr)(2)](n) (1) (Htrtr = 3-(1,2,4-triazolyl-4-yl)-1H-1,2,4-triazole) is synthesized through the hydrothermal reaction of Cu(ClO4)(2) with Htrtr. The crystal structure of 1 is determined by a direct method from X-ray diffraction data (Rigaku Mercury CCD, MoK (alpha) radiation). 1 crystallizes in the monoclinic C2/c space group with unit cell parameters: a = 14.158(2) , b = 9.8050(14) , c = 11.413(3) , beta = 127.9870(10)A degrees, V = 1248.7(4) (3), Z = 4, D (calc) = 1.775 g/cm(3). 1 features a 2D grid based on the propagation of 28-membered rings, which is further fabricated into a 3D supramolecular framework via the hydrogen bond linkage. The fluorescence of 1 shows a blue emission at 441 nm with a 14 nm red-shift compared to that of free Htrtr, which can be assigned to LMCT.
