Die Kristallstruktur des Patronits V(S2)2

The determination of the commensurately modulated structure of tantalum tetratelluride

“…As follows from the structure determinations, TaTe4, NbTe4 (van Smaalen et al, 1986) and the isoelectronic compound VS4 (Allmann et al, 1964) have a high one-dimensional character. Along the chains, the interatomic distances between the metal atoms (Ta, Nb, V) are short compared with the van der Waals radii.…”

The structure of pentaindium tetrasulfide

“…A similar arrangement of metal-metal and (perpendicular) [S-S] 2-pairs as in Ta[PS41S 2] is present in NbESEC12 (von Schnering & Beckmann, 1966) and in VS4 (Allmann, Baumann, Kutoglu & R6sch, 1964).…”

Multiple Redox Modes in the Reversible Lithiation of High-Capacity, Peierls-Distorted Vanadium Sulfide

“…11,12 Vanadium sulfide was discovered as the mineral patronite in 1906. The crystal structure, determined in 1964, 13 revealed that the material is comprised of V 4+ ions coordinated to sulphur dimers forming linear chains extending along the c-axis (Figure 1). No attempt was made however to link the crystal structure of the material to its electronic properties, apart from some early suggestions [14][15][16] ,that VS 4 appeared to display a Peierls distortion.…”

“…55 The V metal formed towards the end of the discharge cycle is similarly nanoparticulate and presumably forms with a large number of defects, the former leading to a large surface to volume ratio. 13 Presumably, the fcc form minimizes the surface energies, 55 which is possibly further facilitated by the occlusion of C atoms into the structure from the electrolyte.…”
