[CH3NH3]4Ga4SbS9S0.28O0.72H: A Three‐Dimensionally Open‐Framework Heterometallic Chalcogenidoantimonate Exhibiting Ni2+ Ion‐Exchange Property

“…The interconnection of [Ga 4 S 9 (QH)] 8− T2 clusters and {SbS 3 } units results in a 3D open framework of [Ga 4 SbS 9 QH] n 4 n − , in which the charge balancing [CH 3 NH 3 ] + cations reside (Figure c). The anionic framework of 1 is similar to that of [NH 3 CH 3 ] 4 In 4 SbS 9 SH except for the composition . Regarding the [Ga 4 S 9 (QH)] 8− T2 clusters and {SbS 3 } units as 3‐connected nodes, the [Ga 4 SbS 9 QH] n 4 n − anionic framework in 1 can be classified as a 10 3 topology (Figure d, Figure S3).…”

“…As shown in Figure , the initial concentration of Ni 2+ ion slowly decreased, and the relative amount of Ni 2+ ion removed reached 74 % after 6 h and increased to almost 100 % after 24 h. The sluggish absorption kinetics may be ascribed to its small pores in 1 , which hinder the fast diffusion of the guest cations. This kinetic behavior was similar to that of Rb + uptake by [NH 3 CH 3 ] 4 In 4 SbS 9 SH . It is interesting that the kinetic data can be analyzed with the pseudo‐second‐order kinetics, which can be described by the Equation . …”

New Members of the Family of In–Sb–S Compounds: Different Roles of Organic Amines

“…By using this method, we recently synthesized the first protonated methylamine-containing 13/15/16 group compound [NH 3 CH 3 ] 4 [In 4 SbS 9 SH]. 44 The high Rb + absorption capacity of this compound demonstrated a significant role of the pore size of the framework on the ion-exchange selectivity. Here, we prepared the new compound 1 through the similar reaction of In 2 S 3 and Sb 2 S 3 in stoichiometric ratio and excessive S powder, nevertheless applying n-propylamine instead of methylamine.…”

“…Recent physical property studies on this family of compounds illustrated that some excellent performances such as selective ion-exchange and photocatalysis were strongly related to their specific compositions and structures. 43,44 In turn, the further improvement of the composition− or structure−function relationships stimulates us all the time to develop the synthetic and structural chemistry of these materials.…”

Effect of alkali cations on two-dimensional networks of two new quaternary thioarsenates (III) prepared by a facile surfactant-thermal method

“…Chalcogenides contain Group 15 elements have been drawing more and more attentions due to their structural diversity [1][2][3][4][5][6], and tremendous potential applications as nonlinear optics [7][8][9], thermoelectric device [10][11][12], ion exchange [13][14][15][16], and photocatalysis [17][18][19]. Thioarsenates(III), a subclass of chalcogenides, typically demonstrate a special structural feature of the stereochemically active 4s 2 lone pair electrons associated with As(III) [1,3].…”
