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].

Two metal-organic frameworks based on the connectivity co-effect between rigid benzenedicarboxylic acid and bridging ligand have been synthesized [Zn 2 (3-NO 2 -bdc) 2 (4,4'-bpy) 2 H 2 O] n (1), [Co(3-NO 2 -bdc)(4,4'-bpy)H 2 O] n (2) (where 3-NO 2 -bdcH 2 = 3-nitro-1,2-benzenedicarboxylic acid, 4,4'-bpy = 4,4'-bipyridine). The two novel complexes were characterized by IR spectrum, elemental analysis, fluorescent properties, thermogravimetric analysis, single-crystal X-ray diffraction and powder X-ray diffraction (PXRD). X-ray structure analysis reveals that 1 and 2 are two-dimensional (2D) network structures. Complex 1 and complex 2 belong to triclinic crystal with P-1 space group. The luminescence measurements reveal that two complexes exhibit good fluorescent emissions in the solid state at room temperature. Also, thermal decomposition process and powder X-ray diffraction of complexes were investigated.
