Four quaternary phosphates of antimony, A3Sb3P2O14⋅3H2O (A=Rb, Cs, Tl and NH4) have been prepared by solid state and hydrothermal reactions and structurally characterized by single crystal and powder X-ray diffraction techniques. They are isostructural with reported K3Sb3P2O14⋅3H2O compound and all five of them have layered structure, wherein the hexagonal-tungsten-oxide (HTO) related (Sb3P2O14)3− anionic layers are interleaved with the A+ ions and water of crystallization. K3Sb3P2O14⋅3H2O undergoes topotactic ion-exchange reactions with aqueous solutions of ACl (A=Rb, Cs, Tl, NH4) salts, almost quantitatively. © 2017 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim

Ten AInM′S4 (A=alkali metals, Tl; M′= Ge, Sn) compounds with diverse structure types have been synthesized and characterized by single crystal and powder X-ray diffraction and a variety of spectroscopic methods. They are wide band gap semiconductors. KInGeS4(1-β), RbInGeS4(2), CsInGeS4(3-β), TlInGeS4(4-β), RbInSnS4(8-β) and CsInSnS4(9) compounds with three-dimensional BaGa2S4 structure and CsInGeS4(3-α) and TlInGeS4(4-α) compounds with a layered TlInSiS4 structure have tetrahedral [InM′S4]- frameworks. On the other hand, LiInSnS4(5) with spinel structure and NaInSnS4(6), KInSnS4(7), RbInSnS4(8-α) and TlInSnS4(10) compounds with layered structure have octahedral [InM′S4]- frameworks. NaInSnS4(6) and KInSnS4(7) compounds undergo facile topotactic ion-exchange, at room temperature, with various mono-, di- and tri-valent cations in aqueous medium to give rise to metastable layered phases. © 2016 Elsevier Inc.
