In the title complex, [CuCl(2)(C(8)H(6)N(2)O)(2)(H(2)O)(2)], the Cu(II) ion is located on an inversion center and is octahedrally coordinated by two N atoms of the 1H-quinazolin-4-one ligand, two chloride ligands and two aqua ligands. The axial Cu-O distances are significantly longer [2.512 (2) Å], than the Cu-N [2.022 (2) Å] and Cu-Cl [2.3232 (4) Å] distances as a result of Jahn-Teller distortion. Aqua ligands are involved in intra- and inter-molecular hydrogen bonding, and N-H⋯O inter-molecular hydrogen bonds are formed between the organic ligands. In addition, weak π-π inter-actions are observed between the benzene rings of the ligand [centroid-centroid distance = 3.678 (1) Å].

A new twofold interpenetrated 3D metal-organic framework (MOF), namely, poly[[μ-aqua-diaqua{μ-2,2'-[terephthaloylbis(azanediyl)]diacetato}barium(II)] dihydrate], {[Ba(CHNO)(HO)]·2HO}, (I), has been assembled through a combination of the reaction of 2,2'-[terephthaloylbis(azanediyl)]diacetic acid (TPBA, HL) with barium hydroxide and crystallization at low temperature. In the crystal structure of (I), the nine-coordinated Ba ions are bridged by two μ-aqua ligands and two carboxylate μ-O atoms to form a 1D loop-like Ba-O chain, which, together with the other two coordinated water molecules and μ-carboxylate groups, produces a rod-like secondary building unit (SBU). The resultant 1D polynuclear SBUs are further extended into a 3D MOF via the terephthalamide moiety of the ligand as a spacer.

2D and 3D porous coordination networks (PCNs) as exemplified by metal-organic frameworks, MOFs, have garnered interest for their potential utility as sorbents for molecular separations and storage. The inherent modularity of PCNs has enabled the development of crystal engineering strategies for systematic fine-tuning of pore size and chemistry in families of related PCNs. The same cannot be said about one-dimensional (1D) coordination polymers, CPs, which are understudied with respect to porosity.

Density functional theory (DFT) calculations indicate that [Co(HO)] reacts with two HO molecules to form [(HO)Co(OOH)(HO)] reactant complexes, which decompose through three distinct pathways depending on the relative orientation between the coordinated OOH and HO ligands. The reactive intermediates produced via these activation pathways include hydroperoxyl (OOH)/superoxide (O) radicals, singlet oxygen (O), and Co(III) species [(HO)Co(O)], [(HO)Co(OH)], and [(HO)Co(OH)]. The Co(III) species display from moderate to strong oxidizing abilities that have long been overlooked.

The crystal structure of the title compound, hexa-aqua-nickel(II) dichloride-1,4,7,10,13,16-hexa-oxa-cyclo-octa-deca-ne-water (1/2/2), [Ni(HO)]Cl·2CHO·2HO, is reported. The asymmetric unit contains half of the Ni(OH) moiety with a formula of CHClNiO at 105 K and triclinic (1) symmetry. The [Ni(OH)] cation has close to ideal octa-hedral geometry with O-Ni-O bond angles that are within 3° of idealized values.
