用水热法合成了2个新的配位聚合物[Zn(3-aba)2]n·nH2O(1)和[Cd(3-aba)2]n(2)(3-aba=间氨基苯甲酸阴离子),对它们进行了元素分析、热分析、红外光谱和X射线单晶衍射等表征。配位聚合物1晶体属正交晶系,Pca21空间群,晶体学数据为:a=0.92626(8)nm,b=1.60073(15)nm,c=1.88522(17)nm,β=90°,V=2.7952(4)nm3,Z=4,μ=1.783mm-1,Dc=1.690g·cm-3,R1=0.0279,wR2=0.0648;配位聚合物2晶体属单斜晶系,P21/n空间群,晶体学数据为:a=0.90068(7)nm,b=0.45203(4)nm,c=1.56802(12)nm,β=106.0750(10)°,V=0.61343(9)nm3,Z=1,μ=1.799mm-1,Dc=2.082g·cm-3,R1=0.0198,wR2=0.0558。在配合物1中,配体分子以双齿配位模式与锌离子配位,而在配合物2中,它以三齿配位模式与镉离子配位。2个配合物均具有二维网状结构。
Two novel coordination polymers [Zn (3-aba) 2] n · nH2O (1) and [Cd (3-aba) 2] n Formic acid anions), which were characterized by elemental analysis, thermal analysis, infrared spectroscopy and X-ray single crystal diffraction. The coordination polymer 1 crystal belongs to orthorhombic, Pca21 space group with crystallographic data of a = 0.92626 (8) nm, b = 1.60073 (15) nm, c = 1.88522 (17) nm, V = 2.7952 (4) nm3, Z = 4, μ = 1.783mm-1, Dc = 1.690g · cm-3, R1 = 0.0279, wR2 = 0.0648. The coordination polymer 2 crystals are monoclinic, n space group, the crystallographic data are as follows: a = 0.90068 (7) nm, b = 0.45203 (4) nm, c = 1.56802 (12) nm, β = 106.0750 = 1, μ = 1.799 mm-1, Dc = 2.082 g-cm-3, R1 = 0.0198, wR2 = 0.0558. In complex 1, the ligand molecule coordinated with zinc ion in bidentate coordination mode, whereas in complex 2 it coordinated with cadmium ion in a three-tooth coordination mode. Both complexes have two-dimensional network structure.
