Synthesis, structures and properties of metal–organic frameworks prepared using a semi-rigid tricarboxylate linker

Abstract

A series of MOFs constructed from 5-((carboxymethyl)amino)isophthalic acid (H3cmai) have been prepared and characterised, with [Cd3(cmai)2(H2O)4]·4H2O demonstrating loss of water in a single-crystal-to-single-crystal transformation.

Three new Zn(ii) coordination polymers for highly selective and sensitive detection of Fe3+

“…The bond length distances of Zn-O range from 1.924 to 2.279 Å, which is consistent with the normal distances of the Zn-O bond length. [46][47][48][49][50][51][52][53] Zn1 and Zn2 are bridged by the O6 atom, while Zn2 and Zn3 are linked with O3W. So a trinuclear metal cluster composed of Zn(II) ions (Zn1, Zn2 and Zn3) is obtained (Fig.…”

Porous Zn-MOF with two diverse cages synthesized using functionalized biphenyl tricarboxylic acid: CO2 selective adsorption and fixation

“…Especially, the ternary carboxylic acids are often used in complex formation due to their unique spatial shock and electron configuration. [20][21][22] For example, the 1,3,5-benzenetricarboxylic acid (H 3 btc) reacts with Zn(II) to form a porous Zn-HKUST-1 complex Zn 3 (btc) 2 with large cells and low accessible porosity. The Zn 2 (COO) 4 paddle wheel clusters are connected by ligands to create a tbo network topology with (3,4) connections, which endows Zn-HKUST-1 unique properties.…”
