1D coordination polymers formed by tetranuclear lead(II) building blocks with carboxylate ligands: In situ isomerization of itaconic acid

Green Synthesis of a New Al‐MOF Based on the Aliphatic Linker Mesaconic Acid: Structure, Properties and In Situ Crystallisation Studies of Al‐MIL‐68‐Mes

“…Moreover a zinc mesaconate is known, which is obtained using itaconic acid (methylenesuccinic acid) . This linker is isomerised in situ to mesaconic acid, and in a similar reaction, a one‐dimensional lead mesaconate coordination polymer was obtained when itaconic acid was employed (Figure ) …”

Crystal structure of trans-bis(2-methylmaleato-κ 2O,O′) bis(piperazinium-κ N) cobalt(II) trihydrate, C18H36CoN4O11

“…Particularly, coordination compounds containing citraconate (2-methylmaleate) or its isomer, mesaconate are known to exhibit interesting electrical and optical properties [4][5][6][7][8]. The crystal structure of the title compound comprises discrete cobalt(II) complex moieties and lattice water molecules.…”

Influence of the ancillary ligand on the crystalline structures and magnetic properties of mesaconato‐bridged Mn coordination polymers

“…Another paper reported, for the first time, the isomerization of itaconic acid to produce mesaconato as bridging ligand, a 2D Zn(II) coordination polymer, [Zn(mes)(dpa)] n (dpa=4,4’‐dipyridylamine), was obtained under solvothermal conditions; and the luminescent properties of this polymer were stated [6] . There is also a paper about a 1D Pb(II) coordination polymer bearing the mesaconato ligand, [Pb 2 (phen) 2 (cit)(mes)] ⋅ 2H 2 O (phen=o‐phenantroline; cit=citraconato), again, the mesaconato ligand was the product of the isomerization of itaconic acid as the synthesis was carried out under solvothermal conditions, the photoluminescent properties of the complex were also reported [7] . Moreover, a zirconium‐mesaconato MOF, with an hexanuclear building unit and a fcu topology, was obtained using a microwave oven by reacting mesaconic acid and ZrOCl 2 ⋅ 8H 2 O in a mixture of water and acetic acid at 95 °C for 5 h under stirring [8] .…”

[8] The 2D polymer {[Zn(mes)(4-nvp) 2 ] • H 2 O} n (4-nvp = 4-(1-naphthylvinyl)pyridine) was synthesized and their crystallography study revealed water dimers inside the rectangular grids of the polymer structure; this polymer showed interesting temperature dependent dielectric properties.…”
