The formula unit of the title one-dimensional coordination polymer, {[Zn(C13H12F2N6O)2(H2O)2](ClO4)2}n, which is twice the asymmetric unit, contains a ZnII ion on an inversion centre, two fluconazole [or 2-(2,4-difluoro­phenyl)-1,3-bis­(1,2,4-triazol-1-yl)propan-2-ol] ligands, two water mol­ecules and two perchlorate anions. The fluconazole ligands connect the ZnII atoms through their N4 atoms in a head-to-tail fashion, resulting in the formation of a one-dimensional cationic macrocyclic chain structure. These one-dimensional cationic chains are connected by hydrogen bonds into a two-dimensional layer structure. There is also a π–π supra­molecular inter­action of the benzene rings of the flucanozole ligands between the chains.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
