TL;DR: A series of zinc(II) coordination polymers with 5-methoxyisophthalate and five related flexible N-donor ancillary ligands, [Zn(CH3O-ip)(bime)0.5] as discussed by the authors, have been synthesized under hydrothermal conditions.
Abstract: A series of zinc(II) coordination polymers with 5-methoxyisophthalate (CH3O–H2ip) and five related flexible N-donor ancillary ligands, [Zn(CH3O-ip)(bime)0.5] (1), [Zn(CH3O-ip)(btx)]2·H2O (2), [Zn(CH3O-ip)(bix)]2 (3), Zn(CH3O-ip)(bib) (4), [Zn2(CH3O-ip)2(bbim)]2 (5) [bime = 1,2-bis(imidazol-1′-yl)ethane, btx = 1,4-bis(triazol-1-ylmethyl)benzene), bix = 1,4-bis(imidazol-1-ylmethyl)benzene, bib = 1,4-bis(2-methyl-imidazol-1-yl)butane, bbim = 1,1′-(1,4-butanediyl)bis(benzimidazole)], have been synthesized under hydrothermal conditions. Complexes 1–5 were structurally characterized by elemental analysis, infrared spectra and X-ray single-crystal diffraction. These complexes display different types of entanglements. Complex 1 features an extended 3D polythreaded network based on 2D coordination frameworks with a (3,4)-connected (42.6)(42.63.8) topology. Complex 2 shows a rare example of entangled coordination polymer containing both interpenetrating and polythreading features. Complex 3 manifests a highly corrugated 2D (4,4) layer. The layers are penetrated by each other to give rise to 3D polycatenations. While 4 and 5 exhibit three-fold interpenetrated 3D 4-connected (65.8) and (3,4)-connected (42.6)(42.6.102.12) topologies, respectively. These results suggest that both 5-methoxyisophthalate and N-donor ancillary ligands influence on the final resulting structures. Furthermore, luminescent properties and thermogravimetric properties of these complexes were investigated.

TL;DR: A porous coordination polymer has been synthesized employing an organic ligand in which a stable free radical, isoindoline nitroxide, is incorporated and was verified to be an efficient, recyclable, and widely applicable catalyst for selective oxidation of various alcohols to the corresponding aldehydes or ketones.
Abstract: A porous coordination polymer (PCP) has been synthesized employing an organic ligand in which a stable free radical, isoindoline nitroxide, is incorporated. The crystalline PCP possesses one-dimensional channels decorated with the nitroxyl catalytic sites. When O2 gas or air was used as the oxidant, this PCP was verified to be an efficient, recyclable, and widely applicable catalyst for selective oxidation of various alcohols to the corresponding aldehydes or ketones.

TL;DR: The luminescent chiral coordination polymer possesses an unprecedented 4-connected uninodal self-catenated three-dimensional 7(4)8(2) network topology, constructed from the interlocking of [Cd(dpa)](n) double helices with [Ct(pht)]( n) single helices.

TL;DR: A novel 2D coordination polymer consisting of ferromagnetic Ni(ii) chains with alternating double EO-azid bridges and (EO-azide)bis(carboxylate) triple bridges exhibits solvent-modulated metamagnetism and the reversible dehydration/hydration processes are accompanied by significant changes in critical temperature, critical field and hysteresis.
