In poly[[bis(μ-4,4′-bi-1H-pyrazole-κ2N2:N2′)bis(3-carboxyadamantane-1-carboxylato-κO1)cobalt(II)] dihydrate], {[Co(C12H15O4)2(C6H6N4)2]·2H2O}n, (I), the Co2+cation lies on an inversion centre and the 4,4′-bipyrazole (4,4′-bpz) ligands are also situated across centres of inversion. In its non-isomorphous cadmium analogue, {[Cd(C12H15O4)2(C6H6N4)2]·2H2O}n, (II), the Cd2+cation lies on a twofold axis. In both compounds, the metal cations adopt an octahedral coordination, with four pyrazole N atoms in the equatorial plane [Co—N = 2.156 (2) and 2.162 (2) Å; Cd—N = 2.298 (2) and 2.321 (2) Å] and two axial carboxylate O atoms [Co—O = 2.1547 (18) Å and Cd—O = 2.347 (2) Å]. In both structures, interligand hydrogen bonding [N...O = 2.682 (3)–2.819 (3) Å] is essential for stabilization of theMN4O2environment with its unusually high (for bulky adamantanecarboxylates) number of coordinatedN-donor co-ligands. The compounds adopt two-dimensional coordination connectivities and exist as square-grid [M(4,4′-bpz)2]nnetworks accommodating monodentate carboxylate ligands. The interlayer linkage is provided by hydrogen bonds from the carboxylic acid groupsviathe solvent water molecules [O...O = 2.565 (3) and 2.616 (3) Å] to the carboxylate groups in the next layer [O...O = 2.717 (3)–2.841 (3) Å], thereby extending the structures in the third dimension.

Organic Framework

Three new metal-organic framework materials [Mg3(LH)2(EtOH)2(H2O)]·(EtOH)4.5(H2O)0.25 (IMP-13Mg), [Co3(LH)2(EtOH)2(H2O)]·(EtOH)3 (IMP-13Co), and [Ca3(LH)2(EtOH)4]·(EtOH)6 (IMP-14) have been prepared from the treatment of silanetetrabenzoic acid (L-H4) with MgII, CoII, and CaII salts respectively. In all cases the silanetetrabenzoic acid has been triply deprotonated and the resultant carboxylate groups assemble with trinuclear metal-based nodes to give (3,6)-connected kgd-type two-dimensional layers. These layers are then extended into the third dimension by coordination of the metal nodes by carboxylic acid groups in adjacent layers. In the case of IMP-13Mg/Co, only alternate L-H connectors and metal nodes are involved in these interlayer interactions, leaving some acid groups free within the structure. However, in IMP-14 all L-H connectors and metal nodes participate in interlayer bonding.

The title compound, {[Ag(C6H7AsNO3)(C18H15P)]·H2O}n, has been synthesized from the reaction of 4-aminophenylarsonic acid with silver nitrate, in aqueous ammonia, with the addition of triphenylphosphane (PPh3). The AgIcentre is four-coordinated by one amino N atom, one PPh3P atom and two arsonate O atoms, forming a severely distorted [AgNPO2] tetrahedron. Two AgI-centred tetrahedra are held together to produce a dinuclear [Ag2O2N2P2] unit by sharing an O–O edge. 4-Aminophenylarsonate (Hapa−) adopts a μ3-κ3N:O:O-tridentate coordination mode connecting two dinuclear units, resulting in a neutral [Ag(Hapa)(PPh3)]nlayer lying parallel to the (10\overline{1}) plane. The PPh3ligands are suspended on both sides of the [Ag(Hapa)(PPh3)]nlayer, displaying up and down orientations. There is anR22(8) hydrogen-bonded dimer involving two arsonate groups from two Hapa−ligands related by a centre of inversion. Additionally, there are hydrogen-bonding interactions involving the solvent water molecules and the arsonate and amine groups of the Hapa−ligands, and weak π–π stacking interactions within the [Ag(Hapa)(PPh3)]nlayer. These two-dimensional layers are further assembled by weak van der Waals interactions to form the final architecture.

The title mononuclear complex, [Nd(C5H3N2O3)3(H2O)3]·3H2O, consists of an NdIIIcation, three 2,4-dioxo-1,2,3,4-tetrahydropyrimidine-5-carboxylate ligands and three aqua ligands forming the neutral complex molecule, and three solvent water molecules. The pyrimidinecarboxylate ligands act in a chelating manner,viacarboxylate and keto O atoms. The NdO9coordination polyhedron is in the form of a distorted monocapped square antiprism. The availability of numerous hydrogen-bonding donors and acceptors results in a very dense hydrogen-bonding network, the immediate effect of which is an unusually large packing index.

In the ZnIIcompound poly[[bis(μ3-cyclohexane-1,3,5-tricarboxylato)bis[μ3-1,3,5-tris(imidazol-1-ylmethyl)benzene]trizinc(II)] hexahydrate], {[Zn3(C18H18N6)2(C9H9O6)2]·6H2O}n, based on mixed 1,3,5-tris(imidazol-1-ylmethyl)benzene and cyclohexane-1,3,5-tricarboxylate ligands, there are two types of crystallographically independent ZnIIcentres, one in a general position and one on a crystallographic twofold axis. They have similar fourfold distorted tetrahedral coordination geometries, ligated by two monodentate carboxylate groups from two cyclohexane-1,3,5-tricarboxylate ligands and by two N atoms from two 1,3,5-tris(imidazol-1-ylmethyl)benzene ligands. The cyclohexane-1,3,5-tricarboxylate anions link the ZnIIcations to generate a two-dimensional layered metal–organic structure running parallel to the (\overline{2}01) plane. Adjacent layers are further connected by tripodal 1,3,5-tris(imidazol-1-ylmethyl)benzene ligands, resulting in a three-dimensional network. The solvent water molecules are linked to the cyclohexane-1,3,5-tricarboxylate ligandsviawater–carboxylate O—H...O hydrogen bonds.

Each CdIIcation in the {[Cd(C8H15N2O2)Cl2]+}nchain is octahedrally coordinated by two pairs of bridging chloride ligands and two O atoms from different bridging carboxylate groups. CdIIcations in the {[CdCl3(H2O)]−}nchain are also octahedrally surrounded by four bridging chloride ligands, one terminal chloride ligand and one coordinated water molecule. Hydrogen bonds between solvent water molecules and these two independent chains generate a three-dimensional framework containing two-dimensional zigzag layers.<!?tpb=18pt>

In the title compound, {[Zn(C6H4O4)(C10H9N3)]·H2O}n, the di(pyridin-2-yl)amine (dpa) ligands chelate the ZnIIions, forming [Zn(dpa)]2+units which are connected by two independent bridging muconate [(2E,4E)-hexa-2,4-dienedioate] ligands to form chains. A crystallographic inversion centre is located at the mid-point of the central C—C bond of each muconate ligand. The carboxylate groups of the muconate ligands bridge the ZnIIions in asymmetric chelating modes. The ZnIIion is coordinated by four O atoms of two chelating carboxylate groups and two pyridyl N atoms in a distorted octahedral coordination environment. In the crystal, N—H...O and O—H...O hydrogen bonds connect chains and solvent water molecules, forming a two-dimensional network parallel to (101).
