Carbonate and phosphite encaged in frameworks constructed from square lanthanum aminopolycarboxylates and sodium chloride

Abstract

Lanthanum aminopolycarboxylates, Na12n[La(edta)L]4n·8nNaCl·4nH2O (1: L = HPO32−; 2: L = CO32−) and K12n[La(cdta)(CO3)]4n·35nH2O (3), with square structures were obtained. Carbonate 2 possesses 3.7 Å diameter holes that can adsorb a small amount of O2 or CO2 selectively.

Highly water-soluble dimeric and trimeric lanthanide carbonates with ethylenediaminetetraacetates as precursors of catalysts for the oxidative coupling reaction of methane

“…For lanthanide carbonato complexes, the common coordination numbers of Ln(III) are 8, 42-44 9, 42,45 and 10. 38,46…”

Solid state structures and solution behaviour of tetranuclear lanthanide(iii) carbonate-bridged coordination compounds of chiral 3 + 3 amine macrocycle

“…While most investigations of the carbonatebridged polynuclear Ln III complexes have been focused on solid state characterization only, [28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46]53 reports concerning detailed solution studies of such compounds are limited. [47][48][49]54,[56][57][58][59][60][61] In fact, some research revealed that the dimeric and trimeric carbonate-bridged polynuclear Ln III complexes may dissociate in solution, resulting in the equilibrium mixture. 47,[56][57][58]…”
