Lanthanide hydrogen-polyphosphates Ln[H(PO3)4] (Ln = Tb, Dy, Ho) were synthesised as colourless (Ln = Tb, Dy) and light pink (Ln = Ho) crystalline powders by reaction of Tb4O7/Dy2O3/Ho2O3 with H3PO3 at 380 °C. All compounds crystallise isotypically (P2(1)/c (no. 14), Z = 4, a(Tb) = 1368.24(4) pm, b(Tb) = 710.42(2) pm, c(Tb) = 965.79(3) pm, β(Tb) = 101.200(1)°, 3112 data, 160 parameters, wR2 = 0.062, a(Ho) = 1363.34(5) pm, b(Ho) = 709.24(3) pm, c(Ho) = 959.07(4) pm, β(Ho) = 101.055(1)°, 1607 data, 158 parameters, wR2 = 0.058). The crystal structure comprises two different infinite helical chains of corner-sharing phosphate tetrahedra. In-between these chains the lanthanide ions are located, coordinated by seven oxygen atoms belonging to four different polyphosphate chains. Vibrational, UV/Vis and fluorescence spectra of Ln[H(PO3)4] (Ln = Tb, Dy, Ho) as well as Dy[H(PO3)4]:Ln (Ln = Ce, Eu) and the magnetic and thermal behaviour of Tb[H(PO3)4] are reported.

Syntheses, Crystal Structures and Optical Spectroscopy of Ln 2 (SO 4 ) 3 ·8H 2 O (Ln: Ho, Tm) and Pr2(SO4)3·4H2O. -Single crystals of the title compounds are prepared by evaporation of aqueous solutions of Ln2O3 (Ln: Ho, Tm, Pr) and H2SO4 at room temperature. Ln2(SO4)3·8H2O (Ln: Ho, Tm) crystallize in the monoclinic space group C2/c with Z = 4 and Pr2(SO4)3·4H2O in the monoclinic space group P21/n with Z = 4. The structures of both the tetra-and octahydrates exhibit a layered arrangement of cations with the sulfate ions in the interlayer space, but differ in the arrangement of the crystal water molecules forming hydrogen bond networks. The Ho-and Pr-compounds are further characterized by IR and UV/VIS spectroscopy. -(KAZMIERCZAK, K.; HOEPPE*, H. A.; J. Solid State Chem. 184 (2011) 5, 1221-1226, http://dx.
