The 2 D coordination polymer network containing fluoroquinolone ligand, {[Cu(L)(bipy)](C2H5OH)(5H2O)}n, was synthesized and its crystal structure was solved. The formula of the complex is C30H40N5FO11Cu and the crystallography data are as follows, monoclinic, space group P21/c(No.14),a=11.937(3)? ,b=10.555(3)? ,c=25.293(9)? ,β =98.82(3)°， V= 3148(1)? 3 and Z=4。 Two carboxylate groups monodentately bind to copper atoms and the 4 oxo group is linked to copper atom. The Cu ion displays a distorted square pyramidal coordination and its coordination number is five.
