Two new coordination polymers,named {[Co_3(pfca)_6(phen)_2]·2H_2O}_n(1) and[Cu(pfca)_2(4,4’-bpy)(H_2O)]_n(2)(Hpfca = 4-fluorocinnamic acid and 4,4-bpy = 4,4-bipyridine),were hydrothermally synthesized and characterized by elemental analysis,IR spectroscopy,thermogravimetric analysis(TGA),and single-crystal X-ray diffraction.Complex 1 crystallizes in the triclinic crystal system,space group P_1 with a = 10.939(3),b = 12.430(4),c = 13.815(4) A,α=78.436(3),β= 70.261(3),γ= 80.268(3)°,V= 1721.8(9) A~3,D_c = 1.508 g/cm~3,M_r= 1564.06,Z = 1,F(000) = 799,μ= 0.802 mm~(-1),the final R = 0.0432 and wR = 0.1015 for 13250 observed reflections with I> 2σ(I).Complex 2 is of monoclinic system,space group P2lc with a =15.4985(14),b = 15.8424(14),c = 10.9528(10) A,β= 107.1600(10)°,V= 2569.6(4) A~3,D_c = 1.468g/cm~3,M_r = 568.02,Z = 4,F(000) = 1164,μ= 0.906 mm~(-1),the final R = 0.0371 and wR = 0.0842 for 18183 observed reflections with I> 2σ(I).Complex 1 features linear Co(Ⅱ)-trinuclear units,which are assembled into a final 3D supramolecular structure through π…π stacking interactions and F-H weak interactions.Complex 2 consists of 1D polymeric Cu(Ⅱ)-chains that are further cohered together by extensive H-bonds.
