Noninterpenetrating Indium Sulfide Supertetrahedral Cristobalite Framework

Frameworks for Extended Solids: Geometrical Design Principles

“…8) and when these are condensed into a framework the stoichiometry is, per unit, ¹ X . Indium sul"de frameworks with the diamond topology have been made both with two interpenetrating nets (39) and without (40); the choice of base neutralizing the In S\ framework is critical in determining whether there is interpenetration or not. The uninterpenetrated structure has very large cavities.…”

Supercubooctahedron (Cs6Cl)2Cs5[Ga15Ge9Se48] Exhibiting Both Cation and Anion Exchange

“…[8] Some examples are T5-MnCd 6 In 28 S 52 (SH) 4 , [5] P2-Li 4 In 22 S 44 , [9] and C3,4-Cd 54 Se 32 (SPh) 48 (H 2 O) 4 . [10] The majority of these compounds contain heavy metals of the fifth period,s uch as In, Sn, or Cd, and those containing light period 4m etals are rare;t he several reported examples include Mn 6 (H 2 O) 3 (m 6 -Se)(GeSe 4 ) 4 , [11] Ge 4 S 10 (TEA-CuGS-SB1), [12] (C 4 NH 12 )Ga 10 S 18 , [13] and [(Zn 4 Ga 16 Se 33 ) 4 (Ga 2.4 Ge 1.6 Se 8 )]-(template) x , [14] of which the isolated 53-atom [Zn 4 Ga 16 Se 33 ]c luster is the largest till now. [14] Usually,t he organic countercations (e.g.,a mine species) are an essential component, simply because the majority of these compounds are crystallized under the influence of an organic template.…”

“…[15] The organic templates can usually be exchanged with alkali metal and raree arth metal cations in solution, albeit with difficulty,w ithin 1o r2d, with degrees of exchange ranging from 50 to 90 %. [16,17] Interestingly, K 6 Sn[Zn 4 Sn 4 S 17 ], whichc ontains three types of Ka toms,s hows high K-exchange selectivity that is determined by site geometry. [18] However,nocompound of this type has shown anion-exchange behavior so far.…”

Chemical vapor transport as a means of controlling the composition of condensed phases

“…The compounds existing in the In-S system (Fig. 12) (InS, In 6 S 7 , and In 2 S 3 ) are low-volatile [49][50][51][52][53][54] (p < 10 Pa at their melting points).…”
