摘      要：A metal-organic coordination polymer [Co(ip)(phen)]n (ip = isophthalate, phen = 1,10-phenanthroline) 1 has been hydrothermally synthesized and characterized. Compound 1 crystallizes in P2/c space group with a = 8.37(2), b = 10.41(1), c = 18.36(3) ?, β = 100.41(7)o, C20H12CoN2O4, Mr = 403.25, V = 1573(4) ?3, Z = 4 and Dc = 1.703 g/cm3. Two Co(II) ions are bridged by μ-carboxylate to form a dinuclear unit, which is extended by ip ligands resulting in a ribbon-like chain. Pairs of phen ligands attach to the dinuclear units on both sides of the chain alternately. Magnetic study reveals that the interaction between the carboxylate-bridged Co(II) ions in 1 is weakly antiferromagnetic.
