Fourteen lanthanide (Ln)-containing hetero selenato-phosphato-peroxopolyoxoniobates in three series: (1) Cs2{[Ln(H2O)4][H4P2Se2Nb6(O2)6O22]}2·nH2O [Ln = Ce (I-Ce), Pr (I-Pr), Sm (I-Sm), Eu (I-Eu), Gd (I-Gd); I-Ce, I-Pr, I-Eu, I-Gdn= 12; I-Smn= 16]; (2) Cs2K3{[Ln(H2O)6][H2.5P2Se2Nb6(O2)6O22]}2·nH2O [Ln = Dy (II-Dy), Tm (II-Tm), Yb (II-Yb), Lu (II-Lu); II-Dyn= 14; II-Tmn= 24; II-Yb, II-Lun= 13]; (3) Cs5K2Hm{[Ln(H2O)6][P2Se2Nb6(O2)6O22]}2{[Lnx(H2O)y]2[P2Se2Nb6(O2)6O22]}·nH2O [Ln = Ho (III-Ho), Er (III-Er), Tm (III-Tm), Yb (III-Yb), Lu (III-Lu), III-Ho-III-Ybm= 5, x= 1; y= 5; III-Lum= 6.5; x= 0.75; y= 4; III-Ho–III-Tmn= 19, III-Ybn= 34; III-Lun= 31], have been isolated by a one-pot reaction and structurally characterized by various physical and chemical analyses. These compounds represent the first group of Ln-functionalized polyoxoniobates with mixed heteroatoms. In addition, the photoluminescence properties of compounds I-Sm, I-Eu, and II-Dywere measured, and the time-resolved emission spectra showed that the {P2Se2Nb6} segment contributed to the energy transfer from the polyoxoniobate units to the Ln3+center, which effectively promoted the emission of the Ln3+center.
