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 dinuclear title compound, [Na2(C13H15ClN5O5S)2(H2O)6] n , two Na+ cations, disposed about a centre of inversion, are linked by two bridging water molecules. The coordination geometry is based on an O5 donor set defined by four water molecules and a 4-aminobenzenesulfonate O atom in a distorted trigonal–bipyramidal geometry. In the crystal, significant O—H...O, O—H...N and N—H...O hydrogen bonds lead to the formation of a three-dimensional architecture.

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.

The asymmetric unit of the title compound, [Li4(C5H3N2O2)4(H2O)4], contains two symmetry-independent LiIions, two symmetry-independent ligands and two symmetry-independent coordinated water molecules. They form a dinuclear unit in which the two LiIions are bridged by two carboxylate O atoms from the two ligands. Two dinuclear units related by an inversion centre form the tetrameric molecule. One of the LiIions shows a distorted tetrahedral coordination geometry, the other a distorted trigonal–bipyramidal environment. The tetramers are held together by hydrogen bonds in which coordinated water molecules act as donors, and the carboxylate O atoms act as acceptors. A hydrogen bond between coordinated water molecule as donor and a ring N atom as acceptor is also observed.

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.

There are three independent CdII ions in the title complex, {[Cd3(C10H3O8)2(H2O)4]·4H2O} n , one of which is coordinated by four O atoms from three 5-carboxybenzene-1,2,4-tricarboxylate ligands and by two water molecules in a distorted octahedral geometry. The second CdII ion is coordinated by five O atoms from four 5-carboxybenzene-1,2,4-tricarboxylate ligands and by one water molecule also in a distorted octahedral geometry while the third CdII ion is coordinated by five O atoms from three 5-carboxybenzene-1,2,4-tricarboxylate ligands and by one water molecule in a highly distorted octahedral geometry. The 5-carboxybenzene-1,2,4-tricarboxylate ligands bridge the CdII ions, resulting in the formation of a three-dimensional structure. Intra- and intermolecular O—H...O hydrogen bonds are present throughout the three-dimensional structure.

The solvothermal reaction of Zn(OAc)2·2H2O with 3,3′-(diazenediyl)dibenzoic acid (H2ADB) in H2O at 393 K afforded the title complex, [Zn(C14H8N2O4)(H2O)]n. The asymmetric unit contains half a ZnIIcation, half an ADB ligand and half a water molecule. Each ZnIIcentre lies on a crystallographic twofold rotation axis and is five-coordinated by four O atoms of bridging carboxylate groups from four ADB ligands and one O atom from a water molecule, forming a distorted trigonal–bipyramidal coordination geometry. The [Zn(H2O)] subunits are bridged by carboxylate groups to give one-dimensional [Zn(μ-COO)4(H2O)]nchains. The chains are linked by ADB ligands into two-dimensional sheets, and these sheets are further connected to neighbouring sheetsviahydrogen bonds (OW—HW...O), forming a three-dimensional hydrogen-bond-stabilized structure with an unprecedented 374175262topology.

In the crystal structure, the pyridine-2,3-dicarboxylate (pydc2−) ligand exhibits μ3-η1,η1:η1:η1and μ3-η1,η1:η1,η1:η1coordination modes, bridging two FeIIIcations and one SrIIcation. The SrIIcation, which is located on an inversion centre, is eight-coordinated by six O atoms of four pydc2−ligands and two water molecules. The coordination geometry of the SrIIcation can be best described as distorted dodecahedral. The FeIIIcation is six-coordinated by O and N atoms of four pydc2−ligands in a slightly distorted octahedral geometry. Each FeIIIcation bridges two neighbouring FeIIIcations to form a one-dimensional [Fe2(pydc)4]nchain. The chains are connected by SrIIcations to form a three-dimensional framework. The topology type of this framework istfj. The structure displays O—H...O and C—H...O hydrogen bonding.

The asymmetric unit of the title compound, [Co(C24H30N2P2)(CO)3][Co(CO)4]·0.25C7H8, consists of two crystallographically independent cations with similar conformations, two anions, and one-half of a toluene molecule disordered about an inversion centre. In the cations, a Co/P/N/P four-membered slightly bent metallacycle is the key structural element. The pendant NH group is not coordinated to the CoIatom, which displays a distorted trigonal–bipyramidal coordination geometry. Weak interionic hydrogen bonds are observed between the NH groups and a carbonyl group of the tetrahedral [Co(CO)4]−anions.
