In the title compound, [Fe(C10H15N2O2)Cl2]·2H2O, the FeIIIion is coordinated by two N and two O atoms of the tetradentate 2-{(2-hydroxyethyl)(pyridin-2-ylmethyl)amino}ethanolate ligand and by two chloride anions, resulting in a distorted octahedral coordination sphere. The average Fe—X(X= ligand N and O atoms) and Fe—Cl bond lengths are 2.10 and 2.32 Å, respectively. In the crystal, duplex O—H...O hydrogen bonds between the hydroxyl and ethoxy groups of two neighbouring complexes give rise to a dimeric unit. The dimers are connected to the lattice water molecules (one of which is equally disordered over two sets of sites) through O—H...Cl hydrogen bonds, forming undulating sheets parallel to (010). Weak C—H...Cl hydrogen bonds are also observed.

In the title compound, [Ni(C12H6O4)(C21H18N4)(H2O)]n, the NiIIcation is coordinated by three carboxylate O atoms of two naphthalene-1,4-dicarboxylate anions, one water molecule and two N atoms of two 1,1′-(9,9-dimethyl-9H-fluoren-2,7-diyl)di-1H-imidazole (DFDI) ligands, giving rise to a slightly distorted octahedral geometry. The NiIIions are linked by the DFDI ligands into chains, which are further connected by the carboxylate anions into double chains that elongate in the theb-axis direction. These double chains are linked by centrosymmetric pairs of O—H...O hydrogen bonds into layers parallel to (10-1). The asymmetric unit consists of one crystallographically independent NiIIcation, one carboxylate and one DFDI ligand, as well as of one water molecule, all of them located in general positions.
