The title complex has been obtained by the reaction of copper nitrate tri-hydrate with 4-abaH (4-abaH=4-aminobenzonic acid) and phenanthroline in ethanol solution,and its structure was determined by X-ray crystallography with the following data: monoclinic,space group C2/c,Mr=1266.13,Cu2C52H54N10O20,a=25.884(5),b=10.205(2),c=20.849(4) ,β=106.34(3)°,Z=4,V=5284.7(18) 3,F(000)=2616,Dc=1.591 g/cm3,μ=0.896 mm-1,the final R=0.0441 and wR=0.1148 for 4200 observed reflections (I > 2σ(I)). In the molecule of the title complex,the asymmetric unit contains one half molecule. The Cu(Ⅱ) atom is five-coordinated by a terminal water molecule,a bidentate phenanthroline and two monodentate 4-aminobenzoate ligands forming a square pyramidal coordination environment. The two bridging 4-aminobenzoate ligands result in a dinuclear copper(Ⅱ) cluster with a short Cu–Cu distance (3.048 ) and a π-π stacking between the adjacent phenanthroline rings (2.96 ).
