Abstract :
The integration of lanthanide(Ln)ions and polyoxoniobates(PONbs)is challenging,and the known Ln-substituted PONbs are still scarce.This work introduces high-nuclear iso-Ln-oxo clusters into the PONb system.The first series of high-nuclear Ln-oxo clusters encapsulated heterometallic polyoxonio-bates Hg[Na(H2O)4l[Cu(en)2]1o{Ln6(μ3-OH)6(SiNb18O54)3}·18H2O(1-Ln,en=ethylenediamine,Ln=Dy,Gd,Tb,Ho,Er,Tm,Yb,Lu)based on flower-like {Ln6(μ3-OH)6(SiNb18O54)3}({Ln6Si3Nb54})clusters have been successfully synthesized via one-pot hydrothermal synthesis strategy.The flower-like polyoxoanion{Ln6Si3Nb54} is consisted of three heteropolyoxoniobate {SiNb18O54} clusters and one unique planar equi-lateral triangle-shaped {Ln6(μ3-OH)6} cluster,which presents the highest nuclear iso-Ln-oxo cluster in PONb chemistry.In {Ln6(μ3-OH)6} cluster,each pair of μ3-OH groups link three Dy3+ions to form a small approximate equilateral triangle-shaped(Dy3(OH)2} cluster.Furthermore,the three {Dy3(OH)2} clusters comprise a bigger approximate equilateral triangle-shaped {Dy6(μ3-OH)6} cluster.The reported hexanu-clear {Ln6} cluster skeletons are mostly octahedral,however,such equilateral triangle-shaped skeleton of the hexanuclear Ln-oxo cluster is first observed.The 1-Dy exhibits good water vapor adsorption capacity and ferromagnetic properties.
