A novel complex [Cd（C9H8O3N）2（2,2′-bipy）（H2O）]2·（H2O）3 with 4-acetylaminobenzoic acid and 2,2′- bipyridine as ligands has been synthesized. Crystal data for this complex are as follows： triclinic, space group P1, a=1.255 9（3） nm, b=1.506 8（3） nm, c=1.650 7（3） nm, α=112.14（3）°, β=101.83（3）°, γ=93.84（3）°, V=2.795 9（10） nm3, Dc=1.592 g·cm-3, Z=4, μ（Mo Kα）=0.840 mm-1, F（000）=1 364, final discrepancy factors R1=0.027 6, wR2= 0.068 3. The asymmetric unit of title complex consists of two separate mono-nuclear structures Cd（C9H8O3N）2（2,2′-bipy）（H2O） and three lattice water molecules. In the complex, the central Cd（Ⅱ） ion is coordinated by two nitrogen atoms,three carboxylic oxygen atoms and one water to give a distorted octahedra coordination geometry . The luminescent and electrochemical properties of the complex are studied.
