Structures of 3,4-dimethyl-2,2',5,5'-tetrathiafulvalene perrhenate, (DMTTF)ReO4, and 3',4'-dimethyl-3,4-tetramethylene-2,5-dithia-2',5'-diselenafulvalene hexafluorophosphate, (CHDTDMDSF)PF6

A series of strongly one-dimensional organic metals with strictly uniform stacks: (o-DMTTF)2X (X = Cl, Br, I)

“…7 However and quite surprisingly, this simple molecule, intermediate between TTF and TMTTF, has not been investigated in detail for electrocrystallization experiments. Only a 1 : 1 insulating salt with ReO 4 − has been structurally characterized 8 and several conducting 2 : 1 salts were reported in 1983. 9 The salts with Br − , I − , SCN − or PF 6 − were reported to be metallic at room temperature with conductivities on the order of 100 S cm −1 , depending on the anion.…”

Hybrid Material Based on the Lindquist Polyoxometalate [W6O19]2− and the organosulfur donor o-Me2TTF: A Combined Structural and Spectroscopic Study

“…Upon oxidation of the o-Me2TTF donor, structural changes in the molecule occur, including the adoption of a planar conformation followed by a lengthening of the central C=C bond and a shortening of the C-S bonds in the central TTF core [50][51][52][53][54][55][56][57][58][59][60]. Using the Coppens' formula, the oxidation state for the o-Me2TTF donors was confirmed to be ?1; this was further confirmed upon comparison of the central C=C and mean C-S bond distances from (o-Me2TTF)2[W6O19] to those for other materials known to contain oxidized o-Me2TTF moieties [29][30][31][32][33][34]47].…”

“…This member of the TTF family has been used by the groups of Dunbar and Fourmigue´ as a starting material to prepare the redox active chelating diphosphine o-P2 used in various homoleptic transition metal coordination compounds [22][23][24][25][26][27][28]. Prior to 2007, the only salt of o-Me2TTF known was (o-Me2TTF) [ReO4] reported in 1993 where it was oxidized to the ?1 oxidation state [29]. Later, the crystal structure of the neutral donor was published in 1998 [30].…”

Decoupling anion-ordering and spin-Peierls transitions in a strongly one-dimensional organic conductor with a chessboard structure, (o-Me2TTF)2NO3

“…Considering the strong interest raised by the halide salts of the o-Me 2 TTF molecule (Fourmigué et al, 2008;Foury-Leylekian et al, 2011), we decided to investigate in more detail its salts with other anions. Before our work on halide salts of o-Me 2 TTF, only a 1:1 insulating salt with ReO 4 À had been structurally characterized (Mhanni et al, 1993), while several conducting 2:1 salts were reported as early as 1983, without X-ray crystal structure resolution, with the BF 4 À , ClO 4 À and SCN À anions (Abderraba et al, 1983). However, all our previous attempts with, for example, BF 4 À , I 3 À (Reinheimer et al, 2009), Re 2 Cl 8 2À (Reinheimer, Galá n-Mascaró s et al, 2008) or W 6 O 19…”
