N-m-cyanophenyl-o-aminobenzoato acid (C15H11N2O2, HNCAB) ligand was synthesized 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 orthorhombic, space group Iba2 with a = 26.422(2), b = 15.1060(2), c = 6.849(1)(A), V= 2733.5(4)(A)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.
