Topological Motifs in Dicyanamides of Transition Metals

Dicyanamides of d-metals provide a wide range of magnetic properties tuned by external cations, encapsulated ions and coordination modes of anions. Analysis of molecular, one-periodic (1D chain), two-periodic (2D layered)...

From lamellar net to bilayered-lamella and to porous pillared-bilayer: reversible crystal-to-crystal transformation, CO2 adsorption, and fluorescence detection of Fe3+, Al3+, Cr3+, MnO4−, and Cr2O72− in water

Layered coordination polymers of different network topologies have showed reversible structural transformations and fluorescence detection toward Fe³⁺, Al³⁺, Cr³⁺, MnO₄^–, and Cr₂O₇^2– in water.

Exploratory studies of a multidimensionally talented simple MnII-based porous network: selective “turn-on” recognition @ cysteine over homocysteine with an indication of cystinuria and renal dysfunction

Solvent-mediated single-crystal-to-single-crystal transformation from a dimeric to tetrameric copper(i) complex based on a substituted pyridine derived from a Diels–Alder adduct

A solution of [Cu₂I₂L₂(MeCN)₂] (1) in dichloromethane (DCM) assisted the removal of MeCN and N-(4-pyridinyl)-9,10-dihydroethanoanthracene-11,12-dicarboximide (L) from the crystal of 1, leading to an unprecedented SCSC transformation.

Construction of metal–organic coordination networks with various metal-linker secondary building units: structures and properties

Three new metal–organic coordination networks with various metal-linker secondary building units are synthesized, which have luminescence and iodine adsorption properties.

Carbon Dioxide Capture by a Metal-Organic Framework with Nitrogen-Rich Channels Based on Rationally Designed Triazole-Functionalized Tetraacid Organic Linker

A semirigid tetraacid linker H4L functionalized with 1,2,3-triazole was rationally designed and synthesized to access nitrogen-rich MOFs for selective adsorption of CO2. The cadmium MOF, that is, Cd-L, obtained by the reaction of H4L with Cd(NO3)2, is found to be a 3D porous framework structure that is robust to desolvation. Crystal structure analysis reveals channels that are decorated by the triazole moieties of L. Gas adsorption studies show that Cd-L MOF permits remarkable CO2 uptake to the extent of 99 and 1000 cc/g at 1 and 30 bar, respectively, at 0 °C. While literature survey reveals that MIL-112, constructed from a 1,2,3-triazole functionalized linker, exhibits no porosity to gas adsorption due to structural flexibility, the results with Cd-L MOF described herein emphasize how rigidification of the organic linker improves gas uptake properties of the resultant MOF.

1D chains, 2D networks and 3D interdigitated frameworks of isoorotic acid or 4,4′-bipyridyl and isoorotic acid: syntheses, structures, and sorption properties
