The UVIatom exhibits a pentagonal–bipyramidal NO6coordination environment, involving two axial oxide ligands [U=O = 1.766 (3) and 1.789 (3) Å], four equatorial O atoms [U—O = 2.269 (3)–2.448 (3) Å] from the ligand and the two coordinated methanol molecules, and one equatorial N atom [U—N = 2.513 (4) Å] from the ligand. In the crystal structure, the complex molecules are linkedviaintermolecular N—H...O and O—H...O hydrogen bonds to form a two-dimensional structure.

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 novel metal–organic framework, {[Zn2Cl4(C25H24N4O4)]·4C3H7NO}n, has been synthesized solvothermally by assembling the semi-rigid tetrahedral ligand tetrakis[(pyridin-4-yl)oxymethyl]methane (tpom) and zinc nitrate in dimethylformamide (DMF). The crystal structure is noncentrosymmetric (P\overline{4}21c). Each ZnIIcation has a tetrahedral coordination environment (C2symmetry), which is formed by two chloride ligands and two pyridine N atoms from two tpom ligands. The tetrahedral tetradentate tpom linker has a quaternary C atom located on the crystallographic \overline{4} axis. This linker utilizes all the peripheral pyridine N atoms to connect four ZnIIcations, thereby forming a wave-like two-dimensional sheet along thecaxis. The two-dimensional layer can be topologically simplified as a typical uninodal 4-connected sql/Shubnikov net, which is represented by the Schläfli symbol {44,62}. Adjacent layers are further packed into a three-dimensional structure by C—H...Cl hydrogen bonds.
