Anion Conformation and Physical Properties in BETS Salts with the Nitroprusside Anion and its Related Ruthenium Halide (X = Cl, Br) Mononitrosyl Complexes: θ-(BETS)4[Fe(CN)5NO], (BETS)2[RuBr5NO], and (BETS)2[RuCl5NO]

Abstract

θ-(BETS) 4 [Fe(CN) 5 NO] (1), (BETS) 2 [RuBr 5 NO] (2), and (BETS) 2 [RuCl 5 NO] (3) [BETS = bis(ethylenedithio)tetraselenafulvalene] have been prepared by electrocrystallisation of BETS using [Fe(CN) 5 NO] 2− or [RuX 5 NO] 2− , X = Cl or Br, as supporting electrolytes and 1,1,2-TCE/ethanol (10 vol%) for 1, nitrobenzene/1,2-DCE (40 vol%)/ethanol (10 vol%) for 2, and benzonitrile/ethanol (10%) solutions for 3 as solvents.Compound 1 exhibits a metallic behaviour down to 40 K, 2 behaves as a semiconductor and 3 as an insulator. The crystal

Radical Salts of Bis(ethylenediseleno)tetrathiafulvalene with Paramagnetic Tris(oxalato)metalate Anions

“…This kind of disorder in the anionic part is not unusual in radical salts of TTF-based donors containing complex anions. For example, similar (not resolved) disorders have also been observed in the radical salts (BETS) 4 [Fe(CN) 5 NO], (BEDO) 4 [Fe(CN) 5 NO], (BET) 4 (NEt 4 ) 2 [Fe(CN) 6 ], and (ET) 3 [MnCr(C 2 O 4 ) 3 ] 5a. In the present case the disorder of the anion has been completely resolved over two interpenetrated positions.…”

Conductive thin films of θ-(BETS) 4 [Fe(CN) 5 NO] on silicon electrodes – new perspectives on charge transfer salts

“…Its crystal and electronic structures have already been reported. 6 The same cell parameters were found whatever the morphology of the crystals. Further characterisation under irradiation are under progress, but they are limited by the difficulty of obtaining sufficient amounts of compound.…”

“…It consists of a thin film made of platelets of irregular shapes but also of diamond-and hexagonal-shaped single crystals as previously evidenced. 6 EDX analysis confirmed the presence of S, Se and Fe within the microcrystals.…”
