The complex monoaqua[(9-hydroxy-fluorene-9-carboxylato)(N,N-Dimethylisopro- panolamine)]copper(II) semihydrate, Cu(C14H8O3)(C5H13NO)(H2O)]0.5H2O (Mr = 417.93), crystallizes in triclinic system, space group P with a = 9.846(2), b =12.419(3), c =16.781(3)? =75.55(3), b = 75.00(3), g = 84.58(3), V =1918.5(7)?, Z = 4, F(000) =872, Dc=1.45g/cm3 and m= 1.17mm-1. The final R and wR are 0.0481 and 0.1427 for 7099 observed reflections, respectively. The coordination polyhedron around the copper atom is a distorted square pyramid, the basal plane consisting of one carboxyl oxygen atom and one -hydroxylated oxygen atom from a 9-hydroxy-fluorene-9-carboxylato ligand, one nitrogen atom and one oxygen atom from the N,N-dimethylisopropanolamine ligand; while the axial coordination site is occupied by a water oxygen atom with a Cu-O bond length of 2.428(3)?
