A series of hydrothermal reactions of ZnX(2) (X = NO(3)(-), ClO(4)(-), and CH(3)COO(-)) with 3-(1,2,4-triazolyl-4-yl)-1H-1,2,4-triazole (Htrtr) with various Zn-Htrtr ratios led to the same 2D metal-organic coordination polymer [Zn(trtr)(2)](n) (1), which features a 2D grid. Four trtr(-) ligands adopting mu(2)-1 kappa N: 1'kappa N mode alternately connect four Zn1 centers to form a 28-membered ring. The growth of the 28-membered rings fuses into the 2D grid, thus, to be further fabricated into a supramolecular framework by hydrogen bondings. The fluorescence of 1 shows an emission peak at 424 nm, which can be assigned to intra-ligand pi-pi transition of trtr.
