Abstract

Two rarely seen 2D coordination polymers based on huge 36-metal pure lanthanide clusters, {[Gd36(NA)36(OH)49(O)6(NO3)6(N3)3(H2O)20]Cl2·28H2O}n (1) and {[Dy36(NA)36(OH)49(O)6(NO3)6(N3)3(H2O)20]Cl2·28H2O}n (2) (HNA = nicotinic acid), were synthesized and structurally characterized. The spherical Ln36 skeleton can be viewed as the aggregation of one cyclohexane chair-like Ln24 wheel and two identical tripod-like Ln6 units. The coordination of the carboxylic groups of the NA ligands with the Ln(III) cations results in a square layer. Additionally, compound 1 possesses a large MCE of 39.66 J kg−1 K−1 and compound 2 exhibits slow relaxation of the magnetization.
