双环[2.2.1]-2-庚烯-5,6-二甲酸镍配合物的合成、晶体结构及热稳定性

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 ℃.
