Mixed-ligands Self-assembly Strategy Affording a New 4-Fold Interpenetrated 3D Co(Ⅱ)-based Coordination Polymer: Synthesis, Crystal Structure and Magnetic Property

摘要

A new Co(Ⅱ)-based coordination polymer,namely [Co(L)0.5(4,4'-bipy)0.5(H2O)2]n (1,H4L =1,3-di(3',5'-dicarboxylphenyl)benzene,4,4'-bipy =4,4'-bipyridine),has been hydrothermally synthesized using the mixed-ligands self-assembly strategy and further fully characterized.The crystal structure is of monoclinic,space group C2/c with a =18.9124(10),b =11.6150(5),c =15.4380(6) (A),β =110.989(5)°,V =3166.2(2) (A)3,C16H13CoNO6,Mr =374.20,Z =8,Dc =1.570 g·cm-3,F(000) =1496,μ =1.116 mm-1,R =0.0461 and wR =0.1312 for 2328 observed reflections (I＞ 2σ(I)).The crystal structure analysis revealed that 1 is a 4-fold interpenetrated three-dimensional (3D) framework with (3,4)-connected dmd-type topology.Moreover,the thermal stability and magnetic property of 1 were also investigated.
