| Abstract: The nickel complex Ni(phen)(H2O)3[C8H11O2(COO)] has been synthesized with bicycle[2.2.1]hept-2-en-5,6-dicarboxylic acid [C7H8(COOH)2] by means of solvent way. It crystallizes in the triclinic space group P1, with a=0.780 58(16) nm, b=1.189 9(2) nm, c=1.214 8(2) nm, α=66.20(3)°, β=88.28(3)°, γ=86.33(3)°, V=1.030 3(4) nm3, Dc=1.554 g·cm-3, Z=2, F(000)=502. Final GOF=1.107, R1=0.026 4, wR2=0.070 2. The crystal structure shows that the nickel ion is coordinated with four oxygen atoms from one bicycle[2.2.1]-2-hepten-5,6-dicarboxylic acid molecule and three water molecules, respectively, with two nitrogen atoms from the 1,10-phenanthroline molecule, forming a distorted octahedral coordination geometry. The result of TG analysis shows that the title complex was stable under 210.0 ℃. CCDC: 741933. |
