| 摘 要： | A coordination polymer based on iron(II) carboxylate helical chains Fe(bpdc)(H2O)2]n 1 has been constructed hydrothermally using H2bpdc (H2bpdc = 2,2'-bipyridine-4,4'-dicarboxylic acid), pyridine and FeSO4·7H2O. Its crystal structure reveals that the Fe(Ⅱ) ion adopts a slightly distorted octahedron. The carboxylates of bpdc ligands alternately bridge the Fe(Ⅱ) cations to form 1D infinite helical chains. The Fe···Fe intrachain distance is 4.8246(6) . The adjacent chains are further interlinked by the coordination of bpdc ligands and hydrogen bonding to form a 3D framework. Magnetic studies for complex 1 show weak antiferromagnetic coupling between the Fe(Ⅱ) ions. The best-fit for χM T vs. T with a Hamiltonian∑∑==iBiiHJSi SigHS11 leadsto g = 2.314(4) and J = -0.68(1) cm-1.
