In the title compound, [Cd(C14H19O4)2(C16H16N4O2)]n, the CdIIcation is coordinated in a distorted octahedral fashion bytranspyridyl N-atom donors from twoN,N′-bis(pyridine-4-carboxamido)piperazine (bpcp) ligands, and chelating carboxylate groups from two 2-[3-(carboxymethyl)adamantan-1-yl]acetate ligands. [Cd(adaH)(bpcp)]ncoordination polymer chains are oriented along [-111] and aggregate into supramolecular layers parallel to (122) by O—H...O hydrogen-bonding interactions. The supramolecular three-dimensional crystal structure is then constructed by interlayer C—H...O non-classical interactions. The O atoms of one of the carboxylate groups were refined as disordered over two sets of sites, with occupancies 0.553 (7) and 0.447 (7).

Form Part

The title compound, {[Zn4(C8H4O4)3(OH)2(C12H6N2O2)2]·2H2O}n, has been prepared hydrothermally by the reaction of Zn(NO3)2·6H2O with benzene-1,4-dicarboxylic acid (H2bdc) and 1,10-phenanthroline-5,6-dione (pdon) in H2O. In the crystal structure, a tetranuclear Zn4(OH)2fragment is located on a crystallographic inversion centre which relates two subunits, each containing a [ZnN2O4] octahedron and a [ZnO4] tetrahedron bridged by a μ3-OH group. The pdon ligand chelates to zinc through its two N atoms to form part of the [ZnN2O4] octahedron. The two crystallographically independent bdc2−ligands are fully deprotonated and adopt μ3-κO:κO′:κO′′ and μ4-κO:κO′:κO′′:κO′′′ coordination modes, bridging three or four ZnIIcations, respectively, from two Zn4(OH)2units. The Zn4(OH)2fragment connects six neighbouring tetranuclear units through four μ3-bdc2−and two μ4-bdc2−ligands, forming a three-dimensional framework with uninodal 6-connected α-Po topology, in which the tetranuclear Zn4(OH)2units are considered as 6-connected nodes and the bdc2−ligands act as linkers. The uncoordinated water molecules are located on opposite sides of the Zn4(OH)2unit and are connected to it through hydrogen-bonding interactions involving hydroxide and carboxylate groups. The structure is further stabilized by extensive π–π interactions between the pdon and μ4-bdc2−ligands.

The crystal structure of the title compound, [Co(C6H4NO2)2(H2O)2]·2H2O, has been reinvestigated with improved precision [previous reports: Chang et al. (1972). J. Coord. Chem. 2, 31–34; Lumme et al. (1969). Suom. Kemistil. B, 42, 270]. In the title compound, the Co atom is located on an inversion center and its coordination can be described as slightly distorted octahedral, equatorially trans-coordinated by two N and O atoms of two picolinate ligands and axially coordinated by two O atoms of the water molecules. Intermolecular O—H...O and C—H...O hydrogen-bonding interactions result in the formation of an intricate three-dimensional network.

In the title compound, [Ni(C4H5NO4)(C10H9N3)(H2O)] n , the NiII cations are octahedrally coordinated by an N atom donor and two O donor atoms belonging to a tridentate iminodiacetate (ida) ligand in a fac fashion, an O atom donor from an aqua ligand, and cis-disposed pyridyl N donor atoms from two 4,4′-dipyridylamine (dpa) ligands. The dpa ligands are disordered over two sets of sites in a 0.594 (7):0.406 (7) ratio. Through the bridging dpa ligands, [Ni(ida)(dpa)(H2O)] n zigzag coordination polymer chains are formed that are oriented along the b-axis direction. These chain motifs are anchored into the three-dimensional supramolecular crystal structure of the title compound by means of O—H...O and N—H...O hydrogen-bonding pathways.

The title compound, [Co(C6H6NO3S)2(H2O)2] n , was obtained from a mixture of Co(NO3)2·6H2O and a previously synthesized salt, namely CyNH3·NH2PhSO3, in a 1:1 ratio (Cy = cyclohexyl; Ph = phenyl). The crystal structure consists of a three-dimensional supramolecular framework, in which polymeric layers are interconnected via N—H...O and O—H...O hydrogen bonding. The polymeric layers are formed by an interconnection of neighbouring cobalt(II) cations via NH2PhSO3 − bridges. Each cobalt(II) cation is surrounded by four NH2PhSO3 − moieties and two water molecules, leading to a distorted octahedral environment.
