用溶液法合成了一种新型的钴配合物[Co2(NDC)2.Phen.H2O]n(NDC=1,4-萘二甲酸根,Phen=1,10-邻菲啰啉),用X射线单晶衍射分析确定了配合物的结构.该配合物属单斜晶系,空间群P21/c,晶胞参数a=0.817 70(5)nm,b=1.944 72(12)nm,c=1.894 43(11)nm,β=101.943 0(10)°,V=2.947 3(3)nm3,Z=4,D=1.678mg/m3,μ=1.192mm-1,F(000)=1 512.该配合物是由1,4-萘二甲酸根桥联而成的三维网络结构,晶体中存在2种Co(Ⅱ)离子,二者都为六配位的变形八面体几何构型,但配位环境不同.配体1,4-萘二甲酸根的配位方式有桥联双齿-桥联三齿和桥联双齿-桥联双齿2种模式,1,10-邻菲啰啉为螯合双齿配体.
A novel cobalt complex [Co2 (NDC) 2.Phen.H2O] n (NDC = 1,4-naphthalate and Phen = 1,10-phenanthroline) The crystal structure of the complex is monoclinic with space group P21 / c, a = 0.817 70 (5) nm and b = 1.944 72 (12) nm, c = 1.89443 (11) nm, β = 101.943 0 (10) °, V = 2.947 3 (3) nm3, Z = 4, D = 1.678mg / m3, μ = 1.192mm-1, F . The complex is a three-dimensional network structure formed by the bridge of 1,4-naphthalene dicarboxylate. There are two kinds of Co (Ⅱ) ions in the crystal, which are both hexacoordinated deformed octahedral geometry. Coordination environment is different.Ligand 1,4-naphthalate coordination mode bridged bidentate - bridged tridentate and bridged bidentate - bridged bidentate two modes, 1,10-phenanthroline The chelate is a chelated bidentate ligand.
