二维网状配位聚合物[Co(NDC)(bpp)(H_2O)]_n的合成
|
摘要
以1,4-萘二酸(H_2NDC)和1,3-二(4-吡啶基)丙烷(bpp)为配体,在水热条件下合成新型配位聚合物[Co(NDC)(bpp)(H_2O)]_n(1).单晶结构分析表明:合成的配合物属单斜晶系,P21/n空间群,晶胞参数:a=1.204 3(2)nm,b=1.311 1(3)nm,c=1.421 55(12)nm,β=103.113(19)°,V=2.185 9(6)nm~3.配合物中Co(Ⅱ)与来自于两个1,4-萘二酸根的三个O原子、两个1,3-二(4-吡啶基)丙烷的两个N原子以及一个水分子的O原子配位,处于变形八面体环境中.Co(Ⅱ)经NDC2-桥连形成一维链状结构,链与链之间通过bpp桥连形成二维网状结构.
One novel Co(II)coordination polymer,[Co(NDC)(bpp)(H_2O)]_n(1)(H2 NDC=1,4-naphthalenedicarboxylic acid,bpp=1,3-bis(4-pyridyl)propane)was synthesized by hydrothermal method with 1,4-naphthalenedicarboxylic acid and 1,3-bis(4-pyridyl)propane as ligands.The single-crystal X-ray diffraction analysis reveals that complex 1 crystallizes in monoclinic,space group P21/n with a = 1.204 3(2)nm,b =1.3111(3)nm,c =1.421 55(12)nm,β= 103.113(19)°,and V = 2.185 9(6)nm~3.The Co(Ⅱ)ion is six coordinated with distorted octahedral coordination geometry by three oxygen atoms from two NDC2-anions,two nitrogen atoms of two bpp ligands and one oxygen from water molecule.In 1,the adjacent Co(Ⅱ)ions are bridged by NDC2-anions to form one dimensional chain.Furthermore,the chains are linked by bpp ligands,resulting in the formation of two-dimensional network.
