A new Co(Ⅱ)coordination polymer,[Co(1,4-chdc)(L)(H20)]n(1),was synthesized under hydrothermal condition(1,4-H2chdc = 1,4-cyclohexanedicarboxylic acid,L =2-(4-fluoro-phenyl)-1 H-imidazo[ 4,5-f] [1,1 O]phenanthroline).Its crystal structure was determined by single-crystal X-ray diffaction.1 crystallizes in triclinic,space group Pl with a = 8.790(5),b=10.486(5),c = 13.305(5)(A),α= 87.391(5),β= 82.925(5),y = 81.841(5)°,V= 1204.2(10)(A)3=2,C27H23FN40SCO,Mr = 561.42,Dc = 1.548 g/cm3,F(OOO)= 578,μ(MoKa)= 0.769 mm-1,R =0.0415 and wR = 0.1043.In 1,each 1,4-chdc anion bridges two neighboring Co(Ⅱ)atoms to give a chain structure.The L ligands are attached on one side of the chain through chelating the Co(Ⅱ)atoms,and are stacked with those of an adjacent chain through π-πinteractions,yielding a double-chain structure.The double-chain structures are linked into a supramolecular layer structure through N-H…O hydrogen-bonding interactions between the adjacent double-chain structures.Moreover,the thermal behavior of 1 was also studied.
