| Abstract: The coordination polymer [Ca(L)2·(CH3OH)2]n (HL=N-phenylanthranilic acid) (1) was synthesized by the reaction of calcium perchlorate with N-phenylanthranilic acid in the CH3OH/H2O. It was characterized by elemental analysis, IR, thermal analysis and X-ray single crystal structure analysis. The crystal of the title complex [Ca(L)2·(CH3OH)2]n belongs to triclinic, space group P1 with a=0.751 5(3) nm, b=1.079 6(4) nm, c=1.629 5(6) nm, α=83.547(5)°, β=89.001(6)°, γ=72.257(5)°, V=1.251 0(8) nm3, Z=2, Dc=1.403 Mg·m-3, F(000)=556, and final R1=0.066 8, wR2=0.140 4. The complex comprises a seven-coordinated calcium(Ⅱ) center, with a O7 distorted pengonal bipyramidal coordination environment. Adjacent Ca(Ⅱ) ions are bridged by N-phenylanthranilicate groups, resulting in a 1D chain structure. The adjacent Ca…Ca distances are 0.382 8 nm and 0.384 6 nm. Furthermore, the molecules are connected by hydrogen bonds to form two dimensional layered structure. CCDC: 652445. |
