Construction of a 3D Co(Ⅱ) Framework Based on Two Types of V-shaped Bidentate Ligands
摘要:
A three-dimensional (3D) coordination polymer {[Co(bdc)(dpb)]·H2O}n (1) was prepared by solvothermal reaction of 1,3-dipyridyl benzene (dpb) with deprotonated 1,3-benzene-dicarboxylate (H2bdc), and was characterized by elemental analysis, IR spectroscopy, and X-ray single-crystal diffraction. It crystallizes in the monoclinic system, space group C2/c with a=15.478(6), b=12.865(5), c=24.091(10) Å, β=95.599(5)°, V=4774(3) Å3, C24H18CoN2O5, Mr=473.34, Dc=1.267 g/cm3, F(000)=1864.0, μ=0.748 mm-1 and Z=8. Each Co(Ⅱ) ion links three bdc2- anions to form an infinitely 1D ladder-shaped chain containing binuclear [(COO)Co]2 cluster, and dpb links adjacent 1D chains to form a 3D pcu framework. In addition, the UV-vis of 1 was also studied.
