Abstract

This is a PDF file of an unedited manuscript that has been accepted for publication. As a service to our customers we are providing this early version of the manuscript. The manuscript will undergo copyediting, typesetting, and review of the resulting galley proof before it is published in its final citable form.

Olenev [a, c] , Wuzong Zhou [b] , Philip Lightfoot [b] and Valery A.Dolgikh [a] similarities to those of known selenite analogs. We discuss the trends in similarities and differences in compositions and structural details between the Se and Te compounds; more members of the family are predicted.

Incorporation of iodine into uranium oxyhydroxide phases

“…48 Salt-inclusion structures typically contain 0D ionic moieties contained within a covalent network structure. Examples of these are often encountered in tellurite halides 49 or rare earth selenites 50 where the lone-pair possessing salt ion often coordinates to the covalent network structure. This is argued to occur in Rb…”

Synthesis, Structures, and Luminescent Properties of Sodium Rare‐Earth Metal(III) Chloride Oxotellurates(IV), Na2Ln3Cl3[TeO3]4 (Ln = Sm, Eu, Gd, Tb, Dy, and Ho)

“…The structures of the sodium rare-earth metal(III) chloride oxotellurates(IV) totally differ from those of halide oxotellurates(IV) containing the larger alkali-metal cations rubidium and cesium. [26] The latter structures demonstrate dissimilar environments for both alkali and rare earth cations: three of four types of Ln 3+ reside in oxygen polyhedra, whereas the fourth occupies [LnO 4 X 4 ] 9square antiprisms. Also, the alkali cations reside in either distorted X 8 or regular O 8 cubes.…”

“…A peculiarity of the M 7 Sm 11 Cl 16 [TeO 3 ] 12 (M = Rb and Cs) compounds is that they are not isostructural to their formal M 7 Sm 11 Cl 16 [SeO 3 ] 12 analogues, but rather to Rb 6 LiLn 11 Cl 16 [SeO 3 ] 12 . [26] The halide tellurites of rare-earth metals with Rb and Cs are evidently different from the corresponding compounds with Na, which are represented by Na 2 Lu 3 I 3 [TeO 3 ] 4 [24] and Na 2 Y 3 Cl 3 [TeO 3 ] 4 . [25] In the current paper, we report synthesis, structures, and luminescent proper-…”

“…In the meantime, until recently, just a handful of oxotellurates(IV), short tellurites, had been described, namely Cs 7 Eu 11 Cl 16 [TeO 3 ] 12 , Na 2 Lu 3 I 3 [TeO 3 ] 4 , and Na 2 Y 3 Cl 3 [TeO 3 ] 4 . Recently, we succeeded in preparation of Cs 7 Sm 11 Cl 16 [TeO 3 ] 12 and Rb 7 Nd 11 Br 16 [TeO 3 ] 12 , isostructural to Cs 7 Eu 11 Cl 16 [TeO 3 ] 12 , as well as a new family of Ln 12 Cd 6 Cl 24 [TeO 3 ] 12 chlorides ( Ln = Sm, Eu, Gd), where a novel [Cd 1‒ x Cl 3 ] building block, sliced from the rock salt structure, has been found. A peculiarity of the M 7 Sm 11 Cl 16 [TeO 3 ] 12 ( M = Rb and Cs) compounds is that they are not isostructural to their formal M 7 Sm 11 Cl 16 [SeO 3 ] 12 analogues, but rather to Rb 6 Li Ln 11 Cl 16 [SeO 3 ] 12 .…”

Bridging the Salt-Inclusion and Open-Framework Structures: The Case of Acentric Ag4B4O7X2 (X = Br, I) Borate Halides

“…Examples of 1D salt inclusions are represented, for instance, by the structures of the above-mentioned Na 3 B 4 O 7 X borate halides (X = Cl, Br), which feature single chains of vertex-sharing XNa 6 octahedra cut out of the rock-salt structures of NaX . Alternations of essentially covalent and ionic layers, which can be considered to be 2D salt-inclusion structures, were observed in the structures of rare-earth selenite and tellurite halides. , Compounds 1 and 2 contribute to the relatively small 3D family represented, e.g., by Pb 2 B 5 O 9 Br (hilgardite) and Ni 3 B 7 O 13 I (boracite) motifs (Figure S7). Note that both nickel and iodine exhibit anharmonic vibrations in the structure of Ni 3 B 7 O 13 I.…”
