“…Previous studies found two stable phases for B 2 S 3 [61,63] with P2 1 /c and I4 1 /a symmetries. However, according to our structural predictions, another B 2 S 3 phase [space group Cc, four formula units per cell; Fig.…”

“…For B-S compounds, most of the current studies are focused on structures and electronic properties at ambient pressure [58][59][60][61][62]. Structural phase transitions of BS and B 2 S 3 have been studied below 50 GPa [63][64][65]. Thus far, their high-pressure phase diagram with a wide range of chemical compositions has not been fully determined yet.…”

Pressure has become an effective way to obtain new materials with desirable properties. Considering the various stoichiometries, wide applications, and unique structures of binary H-S, H-B, and B-S compounds, especially at high pressures, it is worth expecting that they might form ternary compounds with interesting properties as well. Here, phase stabilities of H-B-S ternary compounds, in the pressure range from 0 to 200 GPa, are reliably determined through first-principles unbiased structural search calculations. A hitherto unknown orthorhombic HBS compound with Ama2 symmetry is identified to be stable above 25 GPa, in which B and S atoms alternate to form distorted chains and H atoms are covalently bonded with Bs. With pressure, Ama2 HBS undergoes a semiconductor-to-metal electronic transition and even becomes superconducting. The exploration of the binary B-S phase diagram indicates that B-S compounds tend to decompose into elemental solids above 208 GPa. However, two S-rich phases, B 2 S 3 and BS 2 , are predicted at low pressures, exhibiting semiconducting and metallic properties, respectively. BS 2 shows a calculated T c value of 21.9 K at 200 GPa, becoming a superconductor among bulk binary B-S compounds.

“…Recently new boron sulfides have been synthesized at high pressure i.e. r-BS [2], B2S3 (II) and B2S3 (III) [3]. B2S3 (III) has a tetragonal structure (space group I41/a) based on BS4-tetrahedra, while r-BS is a layered compound with γ-GaS structure (space group R3m, C3v point group).…”

“…The T5 supertetrahedra in LT ‐NaSi 2 P 3 and HT ‐NaSi 2 P 3 lack one Si atom in their centers. This was already observed in other T5 compounds, namely [In 34 S 54 ], 6−[27] LiSi 2 P 3 and HP ‐B 2 S 3 . The infinite connection of SiP 4 supertetrahedra formally gives SiP with sphalerite‐type structure.…”

Fast sodium‐ion conductors are key components of Na‐based all‐solid‐state batteries which hold promise for large‐scale storage of electrical power. We report the synthesis, crystal‐structure determination, and Na+‐ion conductivities of six new Na‐ion conductors, the phosphidosilicates Na19Si13P25, Na23Si19P33, Na23Si28P45, Na23Si37P57, LT‐NaSi2P3 and HT‐NaSi2P3, based entirely on earth‐abundant elements. They have SiP4 tetrahedra assembled interpenetrating networks of T3 to T5 supertetrahedral clusters and can be hierarchically assigned to sphalerite‐ or diamond‐type structures. 23Na solid‐state NMR spectra and geometrical pathway analysis show Na+‐ion mobility between the supertetrahedral cluster networks. Electrochemical impedance spectroscopy shows Na+‐ion conductivities up to σ (Na+)=4×10−4 S cm−1. The conductivities increase with the size of the supertetrahedral clusters through dilution of Na+‐ions as the charge density of the anionic networks decreases.
