Structure of Rhenium Disulfide

Advent of 2D Rhenium Disulfide (ReS2): Fundamentals to Applications

“…Its unit cell is derived from hexagonal symmetry towards a distorted 1T structure, in which Re atoms group into parallelograms of four Re atoms, thereby enabling prodigious possibilities to introduce built-in planar anisotropy into composite heterostructures. [17,24] The added advantages of ReS2 are that it is a flexible semiconductor that has additional possibilities to tune properties with doping and coupling with other materials. [25][26][27] This implies overall that if a 2D ReS2 is wanted as a semiconductor with a given set of properties, it is sure to find one.…”

Molybdenite as a Rhenium Carrier: First Results of a Spectroscopic Approach Using Synchrotron Radiation

“…The crystal structure of rhenium disulphide is a triclinic distortion of CdCl 2 -type basic structure (C19 crystal structure-type [39]) where Re 4+ ions fill two distinct structural sites with approximately octahedral environment by sulphide anions. The structural distortion gives rise to short metal-metal distances configuring Re-Re bonds arranged in [Re 4 ] parallelograms [13]. Despite the occurrence of planar modules [S-Re-S] in rhenium disulphide, the atomic arrangement of Re ions within these layers differs significantly from that observed for [S-Mo-S] layers in the 2H structural array of molybdenite.…”

“…The similarity of XANES spectra conforms to the generally accepted idea that Re 4+ ions present in molybdenite replace Mo 4+ ions in a disordered way, assuming a prismatic coordination like W 4+ ions in WS 2 . As an attempt to certify such replacement, a theoretical simulation of Re L 3 -edge XANES spectrum in rhenium disulphide-a stable compound with a triclinic crystal structure [13]-was carried out using the FEFF program [38]. The crystallographic data used [13] consider two different rhenium atoms; accordingly, XANES functions were calculated for a cluster size of 10 Å, with centers at atom Re 1 and atom Re 2 as absorbers.…”

“…in Japan [2]) as well as in volcanic gases, namely from the Kudryavy Volcano, Kurile Islands [3], but it occurs mainly in ores of porphyry copper-molybdenum deposits [4][5][6][7][8][9] associated to molybdenite, MoS 2 , generally recognized as the main Re-carrier in nature [10,11]. Indeed, specific rhenium minerals are so far confined to very few sulphides among which rheniite, ReS 2 [12]expected to be structurally identical to synthetic rhenium disulphide [13] despite its crystal structure has not yet been fully determined [14], and tarkianite (Cu, Fe) (Re, Mo) 4 S 8 [15], a lacunar kenotetrahedral [16] thiospinel.…”
