Evidence for Cluster Orbital Formation in CsSn2X5 Compounds (X=Cl, Br)

High-Throughput Screening on Halide Perovskite Derivatives and Rational Design of Cs3LuCl6

“…It is possible that alternative compositions with more favorable stability are preferentially formed, or that kinetic processes during synthesis hinder their formation . For the Cs-Sn-X case, as shown in Figure b, we confirmed that it agreed well with synthesis reports, including those for CsSnCl 3 , CsSn 2 Cl 5 , Cs 2 SnCl 6 , Cs 4 SnCl 6 , CsSnBr 3 , Cs 2 SnBr 6 , Cs 4 SnBr 6 , CsSnI 3 , Cs 2 SnI 6 , and Cs 4 SnI 6 . ,,− Despite the complexity of multiphase presence due to multivalent Sn atoms with +2 and +4, the 10 perovskites and derivatives collected above were validated. This demonstrates that our approach is not only thorough in collecting even the elusive perovskite derivatives but also plausible in predicting the synthesizability of halides.…”

New Variant of Highly Symmetric Layered Perovskite with Coordinated NO3− Ligand: Hydrothermal Synthesis, Structure, and Characterization of Cs2PbCl2(NO3)2

“…Thus, attempts have been made to prepare single-crystals of the reaction product to reveal the structure, and we were successful in growing them (see Table ) . On the basis of the single-crystal X-ray diffraction analysis, the structure of CsPb 2 Cl 5 is very similar to that of CsSn 2 Cl 5 . Interestingly, upon adding the alkali metal chlorides to Cs 2 PbCl 2 (NO 3 ) 2 in water, Cs 2 PbCl 2 (NO 3 ) 2 converted to CsPb 2 Cl 5 with the accompanying loss of nitrates.…”

Versatile vapor phase deposition approach to cesium tin bromide materials CsSnBr3, CsSn2Br5 and Cs2SnBr6

“…17), and the few data available refer to crystal structure investigation in single crystals. 19 CsSn 2 Br 5 has a 2D tetragonal crystal structure belonging to the I4/mcm space group, and is composed by two adjacent Sn 2 Br 5 layers separated by a Cs layer along the c-axis. Signicant work has been carried out on the Pb-based counterpart, namely CsPb 2 Br 5 , which is considered a promising candidate for optoelectronic applications.…”
