摘要 A new coordination polymer [Cu2(OH)(nbta)(tib)(H2O)2]n (1) (H3nbta=5-nitro-1,2,3-benzenetricarboxylic acid, tib=1-(4H-1,2,4-triazol-4-yl)-4-(imidazol-1-yl)benzene) constructed from dimeric Cu2 units has been synthesized under hydrothermal condition and structurally characterized by single-crystal X-ray diffraction analysis. The compound crystallizes in monoclinic system, space group I2/c, with a = 17.8474(9), b = 11.7588(6), c = 21.9221(11) ?, β = 104.419(5)°, V = 4455.7(4) ?3, Z = 8. Compound 1 is a three-dimensional structure constructed from dimeric Cu2 units and presents a 2-nodal (3,5)-connected net. What is more, the solid UV–Vis absorption spectra of the compound has also been investigated.

Abstract：A new coordination polymer [Cu2(OH)(nbta)(tib)(H2O)2]n (1) (H3nbta=5-nitro-1,2,3-benzenetricarboxylic acid, tib=1-(4H-1,2,4-triazol-4-yl)-4-(imidazol-1-yl)benzene) constructed from dimeric Cu2 units has been synthesized under hydrothermal condition and structurally characterized by single-crystal X-ray diffraction analysis. The compound crystallizes in monoclinic system, space group I2/c, with a = 17.8474(9), b = 11.7588(6), c = 21.9221(11) ?, β = 104.419(5)°, V = 4455.7(4) ?3, Z = 8. Compound 1 is a three-dimensional structure constructed from dimeric Cu2 units and presents a 2-nodal (3,5)-connected net. What is more, the solid UV–Vis absorption spectra of the compound has also been investigated.
