Construction of a Photocatalytic Cobalt(II) Coordination Polymer with 4-Connected Diamond Topology
摘要:
A novel cobalt(II) coordination polymer, [Co(tdc)(bpmp)(H2O)]n (1), was hydrothermally synthesized using 2,5-thiophenedicarboxylate (tdc) and bis(4-pyridylmethyl)piperazine (bpmp) ligand as the organic linkers. X-ray single-crystal diffraction determination reveals that 1 crystallizes in the monoclinic Cc space group, with a=18.836(2), b=5.9540(7), c=20.414(2) Å, β=97.4300(10)°, V=2270.1(5) Å3, Z=4, Mr=515.44, Dc=1.508 Mg/m3, μ=0.890 mm-1, F(000)=1068, the final R=0.0263 and wR=0.0665 for 3714 observed reflections with I>2σ(I). In compound 1, the Co(II) ions are connected by tdc2- anions to form a 1D double chain, and such chains are further linked by bpmp ligands to form a three-dimensional (3D) structure. Topologically, the structure of 1 represents a uninodal 3D dia (66) topology. What's more, powder X-ray diffraction patterns and photocatalytic property for 1 have also been investigated.
