合成了三种具有一维、二维和三维（1-D、2-D、3-D）无机连接结构的联苯羧酸钡配位聚合物，并对其进行了表征。以联苯-3，3 ′，5，5 ′-四羧酸（H4 BTTC）为配体，合成了具有一维无机连接性（I1 O2）的配位聚合物[Ba 2（BTTC）（H2O）2]n（1，空间群= Pn 21 a，a = 7.059（1）A，B = 12.432（2）A，c = 19.090（3）A）.配位水在270 ℃下强烈配位并被除去。以4，4 ′-联苯二甲酸（H2 BPDC）为配体，[Ba（BPDC）]n（2，空间群= C2/m，a = 6.955（2）A，B = 5.947（1）A，c = 13.852（4）A，β = 92.399（4）°）合成了具有二维无机连接性的配位聚合物（I2 O 1）.每层中Ba-O键的连接在拓扑上类似于CaF 2。以联苯-3，5，5 ′-三羧酸（H3 BPTC）为配体，合成了[Ba 3（BPTC）2（NMF）5 <$2NMF]n（3，空间群= I42 d，a = 25.984（3）A，c = 13.999（2）A）（NMF = N-甲基甲酰胺），并对其进行了结构表征.
The synthesis and characterization of three barium coordination polymers with one-, two-, and three-dimensional (1-D, 2-D, 3-D) inorganic connectivity based on biphenyl carboxylic acid ligands are described. Employing biphenyl-3,3′,5,5′-tetracarboxylic acid (H4BTTC) as a ligand, [Ba2(BTTC)(H2O)2]n (1, space group = Pn21a, a = 7.059(1) A, b = 12.432(2) A, c = 19.090(3) A), a coordination polymer with 1-D inorganic connectivity (I1O2), can be synthesized. The coordinated water is strongly coordinated and removed at 270 °C. By using 4,4′-biphenyldicarboxylic acid (H2BPDC), [Ba(BPDC)]n (2, space group = C2/m, a = 6.955(2) A, b = 5.947(1) A, c = 13.852 (4) A, β = 92.399(4)°) a coordination polymer with 2-D inorganic connectivity (I2O1) is obtained. The connection of the Ba–O bonds in each layer is topologically similar to CaF2. Using biphenyl-3,5,5′-tricarboxylic acid (H3BPTC) as a ligand, [Ba3(BPTC)2(NMF)5⊃2NMF]n (3, space group = I42d, a = 25.984(3) A, c = 13.999(2) A) (NMF = N-methyl formamide), a structur...
