One coordination complex of quinaldic acid and transition metal（Cu） has been synthesized by traditional solution method.It’s composition was determined to be [Cu（C10H6NO2）2（H2O）] by IR, TG analysis and X-ray. The title complex was monoclinic system,belonging to space group P21/c, with a=0.776 28（9） nm, b=0.763 17（16） nm, c=2.956 4（4） nm, β=95.142（11）°, V=1.744 4（5） nm3, Z=4, Mr=425.87, Dc=1.622 mg/m3, R1=0.069 2, w R2=0.124 4. The central Cu2＋ion was in a distorted square pyramid position with five ligating atom and showed a mononuclear complex.
