Analogous Chain Selenite Chlorides Ba2M(SeO3)2Cl2 (M = Cu2+, Ni2+, Co2+, Mn2+) and Pb2Cu(SeO3)2Cl2 with Tunable Spin S: Syntheses and Characterizations

“…19−21 In addition, a nearly ideal 1D chain compound FeF 3 (4,4′-bpy) (4,4′-bpy = 4,4′-bipyridyl) with S = 5/2 shows strong interactions within spin chain, 22 and Fe 2 (TeO 3 ) 2 (SO 4 )•3H 2 O with S = 5/2 exhibits spin-flop transition. 23 with 1D spin chain structures including Cu 3 (CO 3 ) 2 (OH) 2 (S = 1/2), 24 BiCu 2 PO 6 (S = 1/2), 25 Sr 3 NiIrO 6 (S = 1), 26 CaNi 3 P 4 O 14 (S = 1), 27 Co 3 (BPO 4 ) 2 (PO 4 )(OH) 3 (S = 3/ 2), 28 CaCo 2 O 6 (S = 3/2), 29 Co 2 (CH 3 O-ip)(COOH) 2 (H 2 O) (S = 3/2), 30 and SrMn 3 P 4 O 14 (S = 5/2) 31 show a step-like magnetization plateau curve. However, these experimental systems are independent of different crystal structures.…”

“…Thus, the spin value S could significantly affect the magnetic properties. For example, the spin-Peierls transition is observed in CuGeO 3 and NaV 2 O 5 with S = 1/2. , While the screw chain compounds ACo 2 V 2 O 8 (A = Ba, Sr, Pb) with S = 3/2 exhibit various exotic phenomena with spinon confinement, topological excitations, and Bethe strings. − In addition, a nearly ideal 1D chain compound FeF 3 (4,4′-bpy) (4,4′-bpy = 4,4′-bipyridyl) with S = 5/2 shows strong interactions within spin chain, and Fe 2 (TeO 3 ) 2 (SO 4 )·3H 2 O with S = 5/2 exhibits spin-flop transition . Moreover, several compounds with 1D spin chain structures including Cu 3 (CO 3 ) 2 (OH) 2 ( S = 1/2), BiCu 2 PO 6 ( S = 1/2), Sr 3 NiIrO 6 ( S = 1), CaNi 3 P 4 O 14 ( S = 1), Co 3 (BPO 4 ) 2 (PO 4 )­(OH) 3 ( S = 3/2), CaCo 2 O 6 ( S = 3/2), Co 2 (CH 3 O-ip)­(COOH) 2 (H 2 O) ( S = 3/2), and SrMn 3 P 4 O 14 ( S = 5/2) show a step-like magnetization plateau curve.…”
