title: Aqua-{4,4',6,6'-tetra-fluoro-2,2'-[(piperazine-1,4-di-yl)dimethyl-ene]diphenolato}copper(II).
abstract: In the title compound, [Cu(C(18)H(16)F(4)N(2)O(2))(H(2)O)], the Cu(II) atom shows a distorted square-pyramidal coordination geometry with the N,N',O,O'-tetra-dentate piperazine-diphenolate ligand forming the basal plane. The apical site is occupied by the O atom of a coordinated water mol-ecule. Neighbouring complexes are associated through inter-molecular O-H⋯O and O-H⋯F hydrogen bonds between the water mol-ecule and a phenolate O atom or an F atom from an adjacent ligand, respectively, forming a centrosymmetric dimer. Dimers are linked by additional inter-molecular C-H⋯O and C-H⋯F hydrogen bonds, giving infinite chains propagating along the a axis.
