catena-Poly[(di­aqua­cadmium)-μ-iminodi­acetato-κ⁴O,N,O′:O′′]

In the title compound, [Cd(C₄H₅NO₄)(H₂O)₂]_n, the Cd^II atom exhibits a distorted octa­hedral coordination geometry, defined by one N atom and three O atoms from two iminodi­acetate (IDA) ligands and two water molecules. The tridentate IDA ligand additionally bridges via one of its carboxylate O atoms to another Cd^II atom, thus forming a zigzag chain along [001]. A three-dimensional network is completed by inter­molecular O—H...O and N—H...O hydrogen bonds.

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

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-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 Zn^II 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].
