| Abstract: Assembly of 2,3,5,6-tetrabromoterephthalic acid (H2TBTA) with 2,2′-bipyridine (2,2′-bipy) and Cu(NO3)2·3H2O in H2O/CH3OH solution using the layered diffusion method affords a 1D coordination polymer {[Cu(2,2′-bipy)(TBTA)(H2O)]·H2O}n, which has been characterized by elemental analysis, IR spectroscopy, thermogravi-metric analysis, powder X-ray diffraction analysis and single-crystal X-ray diffraction. Complex crystallizes in orthorhombic system, space group Pna21 with a=1.399 9(11) nm, b=0.929 3(7) nm, c=1.557 9(11) nm, V=2.027(3) nm3, Z=4, R1=0.053 5. The central Cu (Ⅱ) ion is five-coordinated, and there are π-π interactions and H-bonding interactions in the complex. The TG analysis shows that the complex is stable below 203 ℃. CCDC: 870487. |
