The title compound, {[ZnCl(C13H12F2N6O)2]Cl·2H2O} n , is a two-dimensional coordination polymer. The Zn(II) atom is six-coordinated by four N atoms from four 2-(2,4-di-fluoro-phen-yl)-1,3-bis-(1,2,4-triazol-1-yl)propan-2-ol (HFlu) ligands and by two Cl atoms in a distorted octa-hedral geometry. Two Cl atoms bridge two Zn(II) atoms, forming a centrosymmetric dinuclear unit. The HFlu ligands connect the dinuclear units into a 4(4) 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 mol-ecules. Intra-layer π-π inter-actions between the triazole rings are observed [centroid-centroid distance = 3.716 (6) Å].

The novel triphenyltin(IV) esters of flufenamic acid (1), Hflu, [Ph(3)Sn(flu)] (2), and of [2-(2,3-dichlorophenylamino)benzoic acid] (3), Hdcpa, [Ph(3)Sn(dcpa)] (4) have been structurally characterized by means of vibrational and (1)H, (13)C NMR spectroscopic studies. The crystal and molecular structures of [SnPh(3)(dcpa)(DMSO)] 4a are described. The molecular structure of 4a reveals that the Sn atom has a distorted trigonal bipyramidal coordination geometry with equatorial phenyl groups and the carboxylate and dimethylsulfoxide oxygen atoms occupying axial positions.
