The adsorption capacity and selectivity of carbon dioxide and nitrogen at 298 K have been evaluated for two series of MMOFs built on metal paddle-wheel building units, including non-interpenetrated Zn(BDC)(TED)(0.5) (1), Zn(BDC-OH)(TED)(0.5) (2), Zn(BDC-NH(2))(TED)(0.5) (3), and interpenetrated Zn(BDC)(BPY)(0.5) (4), Zn(BDC)(DMBPY)(0.5) (5), Zn(NDC)(BPY)(0.5) (6) and Zn(NDC)(DMBPY)(0.5) (7) fra...

The solvothermal synthesis of four two-dimensional metal-organic frameworks containing linear dicarboxylic acids as ligands for Zn(II) centres is described. Zn(BDC)(DMF) [(1) where BDC = benzene-1,4-dicarboxylic acid; DMF = N,N-dimethylformamide] adopts a common paddlewheel motif leading to a 4(4) grid network, whereas Zn(3)(BDC)(3)(EtOH)(2) (2), Zn(3)(BDC)(3)(H(2)O)(2) * 4DMF (3) and Zn(3)(BPD...

A series of mixed-ligand coordination complexes, namely [Zn(CA)(2)(BIE)] (1), [Zn(OX)(BIE)].H(2)O (2), [Zn(2)(m-BDC)(2)(BIE)(2)] (3), [Cd(m-BDC)(BIE)] (4), [Cd(5-OH-m-BDC)(BIE)] (5), [Zn(5-OH-m-BDC)(BIE)] (6), [Zn(2)(p-BDC)(2)(BIE)(2)].2.5H(2)O (7), [Cd(3)(p-BDC)(3)(BIE)] (8), [Cd(3)(BTC)(2)(BIE)(2)].0.5H(2)O (9) and [Zn(BTCA)(0.5)(BIE)] (10), where CA = cinnamate anion, OX = oxalate anion, m-B...

The three-dimensional polymeric title compound, {[Zn(C(9)H(4)N(2)O(4))]·H(2)O}(n), contains one crystallographically independent Zn(II) atom, one fully deprotonated 1H-benzimid-azole-5,6-dicarboxyl-ate (bdc) ligand and one uncoordinated water mol-ecule. The Zn(II) atom is four-coordinated by three O atoms and one N atom from the bdc ligands, giving a distorted tetra-hedral coordination geometry...

A systematic modulation of organic ligands connecting dinuclear paddle-wheel motifs leads to a series of isomorphous metal-organic porous materials that have a three-dimensional connectivity and interconnected pores. Aromatic dicarboxylates such as 1,4-benzenedicarboxylate (1,4-bdc), tetramethylterephthalate (tmbdc), 1,4-naphthalenedicarboxylate (1,4-ndc), tetrafluoroterephthalate (tfbdc), or 2...

Zinc(II) nitrate reacts with different ratios of 1,4-benzenedicarboxylic acid (H(2)bdc) and 2-halo-1,4-benzenedicarboxylic acid (H(2)bdc-X, X = Br or I) to give [Zn(4)O(bdc)(3-x)(bdc-X)(x)], in which preferential incorporation of bdc is observed. The selective incorporation is related to crystal growth rates, and the proportion of incorporated bdc-X rises with increasing reaction time.

In the crystal structure of the title compound, [Zn(4)(C(8)H(4)O(4))(4)(C(8)H(12)N(6))(H(2)O)(4)](n), one Zn(II) atom is four-coordinated in a slightly distorted tetra-hedral geometry by two O atoms from benzene-1,3-dicarboxyl-ate (BDC) ligands, one N atom from a 1,4-bis-(1,2,4-triazol-1-yl)butane (BTB) ligand and one water mol-ecule, while a second Zn(II) atom is five-coordinated in a distorte...

Electroreduction of oxoanions affords hydroxide equivalents that induce selective deposition of crystalline metal-organic frameworks (MOFs) on conductive surfaces. The method is illustrated by cathodic electrodeposition of Zn(4)O(BDC)(3) (MOF-5; BDC = 1,4-benzenedicarboxylate), which is deposited at room temperature in only 15 min under cathodic potential. Although many crystalline phases are k...

Nanoscale titania particles were synthesized inside the porous coordination polymer [Zn(4)O(bdc)(3)] (bdc = 1,4-benzene-dicarboxylate, MOF-5) by adsorption of titanium isopropoxide from the gas-phase and subsequent dry oxidation and annealing.

Reactions of zinc sulfate and (R)- or (S)-(1-phenylethylamino)methylphosphonic acid (pempH(2)) in the presence of 1,4-benzenedicarboxylic acid (H(2)bdc) result in homochiral enantiomers (R)- and (S)-[Zn(4)(pempH)(4)(bdc)(2)].2H(2)O (). When H(2)bdc is replaced by 1,2,4,5-benzenetetracarboxylic acid (H(4)btec), enantiomers (R)- and (S)-[Zn(3)(pempH)(2)(btec)(H(2)O)(2)].H(2)O () are obtained. Com...
