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, [Rh(C6H5N4)Cl2(C12H27P)2], the RhIIIion is chelated by the singly deprotonated 2,2′-biimidazolate (Hbim−) ligand and coordinated by two chloride ions and two tri-n-butylphosphane ligands. The chloride ions and N atoms of the Hbim−ligand lie in a plane where the sum ofX—Rh—Xangles betweencissites is 360°. The phosphane ligands occupy the sites perpendicular to the plane, completing the overall distorted octahedral coordination sphere. The complex forms a self-complementary hydrogen-bonded dimer with the inversion-related complex through N—H...N hydrogen bonds.

Trigonal Prismatic

In the title compound, [Tb(C2H3O2)2(C11H10N4)(H2O)2]NO3·H2O, the Tb3+ ion is nine-coordinated in a distorted tricapped trigonal-prismatic geometry by the three N atoms of the tridentate 1-(pyridin-2-ylmethylidene)-2-(pyridin-2-yl)hydrazine ligand, four carboxylate O atoms of two chelating acetate groups and two O atoms of the coordinating water molecules. The organic hydrazine ligand is disordered over two orientations with a refined occupancy ratio of 0.52 (3):0.48 (3). All bond lengths in the coordination environment of the Tb3+ ion are slightly larger than those observed in the isostructural Y3+ and Er3+ complexes. In the crystal, the complex cations are linked by pairs of O—H...O hydrogen bonds into dimers. These dimers, nitrate anions and non-coordinating water molecules are joined by O—H...O and N—H...O hydrogen bonds into a three-dimensional structure.

A Chain

In the title compound, [Cu2(C7HF4O2)4(C12H8N2)2]·2H2O, the CuIIion has a square-pyramidal coordination sphere. The basal plane consists of two N atoms [Cu—N = 2.008 (3) and 2.032 (3) Å] from the phenanthroline ligand, and of two carboxylate O atoms [Cu—O = 1.942 (3) and 1.948 (3) Å] from two 2,3,4,5-tetrafluorobenzoate anions. Another 2,3,4,5-tetrafluorobenzoate anion provides the apical carboxylate O atom [Cu—O = 2.262 (3) Å] and bridges two CuIIions into a binuclear centrosymmetric dimer. Intramolecular π–π interactions between one of the tetrafluorobenzene rings and the middle of the phenenanthroline rings [3.617 (3) Å] stabilize the molecular configuration. O—H...O hydrogen bonds between the lattice water molecules and the unbound carboxylate O atoms of the metal complexes leads to the formation of a chain structure parallel to [100].
