Poly[[μ-chlorido-μ-[2-(2,4-difluorophenyl)-1,3-bis(1,2,4-triazol-1-yl)propan-2-ol-κ2N4:N4′]-zinc] chloride dihydrate]

Abstract

The title compound, {[ZnCl(C13H12F2N6O)2]Cl·2H2O}n, is a two-dimensional coordination polymer. The ZnII atom is six-coordinated by four N atoms from four 2-(2,4-difluorophenyl)-1,3-bis(1,2,4-triazol-1-yl)propan-2-ol (HFlu) ligands and by two Cl atoms in a distorted octahedral geometry. Two Cl atoms bridge two ZnII atoms, forming a centrosymmetric dinuclear unit. The HFlu ligands connect the dinuclear units into a 44 net parallel to (001) when the dinuclear unit is considered as a node. O—H...O and O—H...Cl hydrogen bonds link the cationic layer, free chloride anions and lattice water molecules. Intralayer π–π interactions between the triazole rings are observed [centroid–centroid distance = 3.716 (6) Å].
