The structure of the title compound, [Li2(C8H2N2O8)(H2O)4]·H2O, is composed of dinuclear molecules in which the ligand bridges two symmetry-related LiIions, each coordinated also by two water O atoms, in anO,N,O′-manner. The Li and N atoms occupy special positions on twofold rotation axes, whereas a crystal water molecule is located at the intersection of three twofold rotation axes. The LiIcation shows a distorted trigonal–bipyramidal coordination. Two carboxylate groups remain protonated and form short interligand hydrogen bonds. The molecules are held together by a network of hydrogen bonds in which the coordinating and solvation water molecules act as donors and carboxylate O atoms as acceptors, forming a three-dimensional architecture.

The structure of the title compound, {(N2H5)[Li3(C6H2N2O4)2(H2O)2]·H2O}n, is composed of molecular dimers, each built up of two symmetry-related LiIions with distorted trigonal–bipyramidal coordinations bridged by two deprotonated ligand moleculesviatheirN,O-bonding sites. Doubly solvated LiIions with a distorted tetrahedral geometry link adjacent dimers, forming a polymer generated by bridging bidentate carboxylato O atoms to LiIions in adjacent dimers, forming anionic layers parallel to theacplane with monoprotonated hydrazinium cations and crystal water molecules positioned between them. The layers are held together by an extended system of hydrogen bonds in which the hydrazinium cations and coordinated and crystal water molecules act as donors and carboxylate O atoms act as acceptors.

The title compound, [CdBr2(C13H12N4O)], was obtained from the reaction of Cd(NO3)2·4H2O with methyl(pyridin-2-yl)methanone picolinoylhydrazone and sodium bromide. The Cd2+ cation is ligated by one O atom and two N atoms of the tridentate ligand and two bromide anions, forming a Br2CdN2O polyhedron with a distorted trigonal–bipyramidal coordination geometry. In the crystal, non-classical C—H...Br hydrogen bonds are observed. In addition, π–π stacking interactions [centroid–centroid distance = 3.7455 (19) Å] contribute to the stabilization of the crystal structure.

The asymmetric unit of the title MOF, [Zn5(C14H5NO10S2)2(OH)2(H2O)10] n comprises three ZnII atoms, one of which is located on a centre of inversion, a tetra-negative carboxylate ligand, one μ 3-hydroxide and five water molecules, each of which is coordinated. The ZnII atom, lying on a centre of inversion, is coordinated by trans sulfoxide-O atoms and four water molecules in an octahedral geometry. Another ZnII atom is coordinated by two carboxylate-O atoms, one hydroxy-O, one sulfoxide-O and a water-O atom to define a distorted trigonal–bipyramidal geometry; a close Zn...O(carboxylate) interaction derived from an asymmetrically coordinating ligand (Zn—O = 1.95 and 3.07 Å) suggests a 5 + 1 coordination geometry. The third ZnII atom is coordinated in an octahedral fashion by two hydroxy-O atoms, one carboxylate-O, one sulfoxide-O and two water-O atoms, the latter being mutually cis. In all, the carboxylate ligand binds six ZnII ions leading to a three-dimensional architecture. In the crystal, all acidic donors form hydrogen bonds to oxygen acceptors to contribute to the stability of the three-dimensional architecture.

In the title compound, {[Co(C14H8N2O5)(C10H8N2)]·3H2O}n, the CoIIcation is five-coordinated with a slightly distorted trigonal–bipyramidal geometry, and the 5-isonicotinamidoisophthalate ligands link CoIIatoms into a layered structure. These two-dimensional arrays are further pillared by rod-like 4,4′-bipyridine ligands to give a three-dimensional framework with pcu (primitive cubic) topology.

The three-dimensional coordination polymer poly[[bis(μ3-2-aminoacetato)di-μ-aqua-μ3-(naphthalene-1,5-disulfonato)-hexasilver(I)] dihydrate], {[Ag6(C10H6O6S2)(C2H4NO2)4(H2O)2]·2H2O}n, based on mixed naphthalene-1,5-disulfonate (L1) and 2-aminoacetate (L2) ligands, contains two AgIcentres (Ag1 and Ag4) in general positions, and another two (Ag2 and Ag3) on inversion centres. Ag1 is five-coordinated by three O atoms from oneL1 anion, oneL2 anion and one water molecule, one N atom from oneL2 anion and one AgIcation in a distorted trigonal–bipyramidal coordination geometry. Ag2 is surrounded by four O atoms from twoL2 anions and two water molecules, and two AgIcations in a slightly octahedral coordination geometry. Ag3 is four-coordinated by two O atoms from twoL2 anions and two AgIcations in a slightly distorted square geometry, while Ag4 is also four-coordinated by two O atoms from oneL1 and oneL2 ligand, one N atom from anotherL2 anion, and one AgIcation, exhibiting a distorted tetrahedral coordination geometry. In the crystal structure, there are two one-dimensional chains nearly perpendicular to one another (interchain angle = 87.0°). The chains are connected by water molecules to give a two-dimensional layer, and the layers are further bridged byL1 anions to generate a novel three-dimensional framework. Moreover, hydrogen-bonding interactions consolidate the network.
