摘要
N-m-cyanophenyl-o-aminobenzoato acid（C15H11N2O2,HNCAB） ligand was syn-thesized through the bromination and nucleophilic reactions.The compound [K（NCAB）]n（1） was synthesized via the hydrothermal reaction of CuSO4,KCO3 and HNCAB,and characterized by elemental analysis,infrared spectra,and X-ray diffraction.The complex crystallizes in orthorho-mbic,space group Iba2 with a = 26.422（2）,b = 15.1060（2）,c = 6.849（1） ,V = 2733.5（4） 3,Z = 8,C15H11KN2O2,Mr = 290.36,Dc = 1.411 g/cm3,F（000） = 1200 and μ（MoKα） = 0.390 mm-1.The final R = 0.0329 and wR = 0.0788 for 2644 observed reflections with Ⅰ〉 2σ（Ⅰ） and R = 0.0397 and wR = 0.0826 for all data.Each carboxylato of NCAB ligand is coordinated to four K ions in an unprecedented μ4-κ2,κ1,κ1,κ1 coordination mode to form a 1-D tube-chain along the c axis.These 1D tube-chains are assembled into an unprecedented 3D framework via K-N bonds.The network of compound 1 exhibits a relatively rare five-connected topology.
