Abstract A novel zinc coordination polymer, [Zn 3 (pdc) 2 (bib) 2.5 (H 2 O) 2 ] n ·4nH 2 O·0.5 n bib (H 3 pdc = 3,5-pyrazoledicarboxylic acid, bib =1,4-bis(imidazol-1-ylmethyl)butane), has been synthesized through hydrothermal methods and characterized structurally by single-crystal X-ray diffraction. The polymer crystallizes in a triclinic space group P 1 ¯ P\bar{1} , with unit cell parameters of a = 12.5612, b = 12.8928, c = 16.5488 Å, α = 105.556°, β = 102.193°, γ = 93.817°, and Z = 2. Zinc( ii ) ions possess trigonal bipyramidal coordination, connecting different pdc 3− anions to form tri-nuclear subunits. These subunits are linked to 2D networks via bib ligands. Additionally, the fluorescence properties of 1 have been examined.
