“…The averaged distances are 2.390(4), 2.387(4), 2.419(4), and 2.408(4) Å for Cr(1), Cr(2), Cr(3), and Cr (4) The face-sharing CrS 6 structure has short Cr-Cr distances of 2.995(3) Å (Cr(1)-Cr (3) The coordination octahedra around the Cr(1) and Cr(2) atoms in the CrS 2 sheets are almost regular. The bond angles of S-Cr-S are in the range from 84.1(1) to 96.1 (1) . However, the Cr(3) and Cr(4) octahedra are more distorted.…”

“…However, the Cr(3) and Cr(4) octahedra are more distorted. The S-Cr-S bond angles around Cr(3) and Cr(4) are in the range from 82.1(1) to 100.1 (1) and 81.1(1) to 99.0(1) , respectively. This distortion around Cr(3) and Cr(4) is due to the structural strain arising from the compact face-sharing linkages of CrS 6 octahedra in this compound.…”

“…17 We have prepared two chromium sulfides with 1-D structures, Ba 3 CrS 5 , and Ba 3 Cr 2 S 6 at high pressures and high temperatures. 1 These sulfides, having structures that are closely related to BaNiO 3 , [18][19][20] structure and can be prepared only by high-pressure synthesis method. Reaction conditions of the high-pressure synthesis method are completely different from any other conventional ones using evacuated ampoules or floating CS 2 or H 2 S gases.…”

Two new ternary barium chromium sulfides, BaCr 4 S 7 and Ba 2 Cr 5 S 10 , were synthesized by reactions of barium sulfide, sulfur, and chromium metal under high-pressure and high-temperature conditions. Single crystals of BaCr 4 S 7 were obtained from a starting mixture with a molar ratio of Ba:Cr:S = 2:5:10 after reacting at 1200 C and under a pressure of 5 GPa. It crystallizes in the monoclinic space group P2 1 =c (No. 14) with a ¼ 6:739ð4Þ Å , b ¼ 22:665ð9Þ Å , c ¼ , V ¼ 683:1ð9Þ Å 3 , and Z ¼ 2. The structure is composed of CrS 2 sheets and the wall-shaped subunits, like as in BaCr 4 S 7 , but the subunits do not connect the adjacent CrS 2 sheets. It has a two-dimensional structure, and Ba atoms are situated in interlayer regions.

“…131 The reaction of sulfur, barium sulfide and chromium metal under a high pressure of 5 GPa at 1200 uC results in the synthesis of two new ternary chromium sulfides, Ba 3 CrS 5 and Ba 3 Cr 2 S 6 . 132 Hexagonal Ba 3 CrS 5 has a column structure with one-dimensional chains of [CrS 3 ] ' composed of face-sharing CrS 6 octahedra surrounded with Ba 21 ions. Ba 3 Cr 2 S 6 is trigonal and contains [CrS 3 ] ' chains that are composed of octahedral and trigonal-prismatic CrS 6 units which are alternately stacked in a face-sharing manner.…”

A Ferrotoroidic Candidate with Well‐Separated Spin Chains

et al. 2022

The search of novel quasi‐1D materials is one of the important aspects in the field of material science. Toroidal moment, the order parameter of ferrotoroidic order, can be generated by a head‐to‐tail configuration of magnetic moment. It has been theoretically proposed that 1D dimerized and antiferromagnetic (AFM)‐like spin chain hosts ferrotoroidicity and has the toroidal moment composed of only two antiparallel spins. Here, the authors report a ferrotoroidic candidate of Ba6Cr2S10 with such a theoretical model of spin chain. The structure consists of unique dimerized face‐sharing CrS6 octahedral chains along the c axis. An AFM‐like ordering at ≈10 K breaks both space‐ and time‐reversal symmetries and the magnetic point group of mm′2′allows three ferroic orders in Ba6Cr2S10: (anti)ferromagnetic, ferroelectric, and ferrotoroidic orders. Their investigation reveals that Ba6Cr2S10 is a rare ferrotoroid ic candidate with quasi 1D spin chain, which can be considered as a starting point for the further exploration of the physics and applications of ferrotoroidicity.
