Anionic Polymeric Bonds in Nickel Ditelluride: Crystal Structure, and Experimental and Theoretical Band Structure

Electronic transport and magnetic properties of a new nickel antimonide telluride, Ni2SbTe2

“…Since both NiSb and NiTe 2 exhibit metallic behavior [39][40][41][42], we might expect similar behavior from Ni 2 SbTe 2 . Fig.…”

An Electron and X-Ray Diffraction Investigation of Ni1+xTe2 and Ni1+xSe2CdI2/NiAs Type Solid Solution Phases

“…The fact that the z fractional coordinate of the Te ion in stoichiometric NiTe (9,12) is very close to (indeed it remains close to right across the whole solid solution "eld (12)) ensures that the thickness of the fully occupied Te}Ni }Te layer has essentially the same width as the (nickel vacant) Te}Ni }Te layer. In conjunction with the low c/a ratio (&1.365) and consequent short interlayer (&&through layer'' as well as &&through gap'') Te}Te distances (7,9), it seems clear that interlayer Te}Te bonding is playing an important role in determining the thickness of the layers and hence the magnitude of the c axis.…”

Unconventionally Layered CoTe2 and NiTe2 as Electrocatalysts for Hydrogen Evolution

“…Each TMD layer containsr epeating units of MX 2 that are covalently linked whereas van der Waals interactions exist between loosely stacked layers of MX 2 .C rowned as the prototype of TMDs, MoS 2 exudes anisotropy;i ne lectronic,m echanical and electrochemicala spects, [3] that catapulted the realm of TMDs to the spotlighti nt he scientific community.R esonating with the versatile properties of MoS 2 ,T MDsh ave gained traction acrossa myriad of applicationsi ncluding batteries, supercapacitors, photovoltaics, and sensors. [5] Proceeding down the group from sulfur to tellurium decreases the electronegativity of the chalcogen and raises the energy level of the anionic sp valence band. Despite the weak lustre of ditelluride research, electronic and bondingp roperties of the transition metal ditellurides come across as more intriguing thant he disulfides or diselenides.…”

“…[3b, 4] Closeri nspection of the TMD research to date reveals tremendouse mphasis on transition metal disulfides and diselenides, whereas the ditelluride family remains in their shadows. [5] Ta ken together,t he lowered db and levels of the transition metal and the increased sp band energy of the chalcogen facilitate cationic-anionic redox interactions within the structure. As exemplified in 1T-MoS 2 and -WSe 2 ,aTMD usually adopts aC dI 2 layered phase whereby the transition metal centeri sc oordinated to 6o ther chalcogen atoms in an octahedral geometry.…”
