This study reports the experimental realization of Nb2CTe2, the first tellurium-based TMCC phase. Using a sealed-ampule reactive synthesis strategy, Nb2CTe2 was obtained as the predominant phase (78.0 wt %). X-ray diffraction, scanning electron microscopy, together with atomic-resolution scanning transmission microscopy structural and chemical analysis, confirm a layered trigonal structure (P3\u0305m1) and lamellar flake-like morphology composed of Nb\u2013C slabs capped by Te layers. High-angle annular dark-field scanning transmission electron microscopy-derived interlayer separation, together with the previously predicted low delamination energy, supports weak out-of-plane vdW coupling. Long-term ambient exposure revealed limited chemical stability in air, with near-complete loss of the Nb2CTe2 phase, increased diffuse scattering, and oxidative degradation over time. This work expands the experimentally accessible TMCC family to Te-containing compositions and provides a foundation for future studies of heavy-chalcogen TMCCs and their two-dimensional derivatives.<\/jats:p>","DOI":"10.1021\/acsomega.6c02686","type":"journal-article","created":{"date-parts":[[2026,8,4]],"date-time":"2026-08-04T13:18:28Z","timestamp":1785849508000},"page":"46136-46142","source":"Crossref","is-referenced-by-count":1,"title":["Extending Transition-Metal\nCarbo-Chalcogenides to\nTellurium with Nb2CTe2"],"prefix":"10.1021","volume":"11","author":[{"given":"Yiftach","family":"Kushnir","sequence":"first","affiliation":[{"name":"Tel Aviv University , , P.O.B 39040, Ramat Aviv, ,","place":["Tel Aviv-Yafo, Israel, 6997801"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mark","family":"Baranov","sequence":"additional","affiliation":[{"name":"Ben-Gurion University of the Negev , , P.O.B 653, ,","place":["Beer-Sheva, Israel, 8410501"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bar","family":"Favelukis","sequence":"additional","affiliation":[{"name":"Tel Aviv University , , P.O.B 39040, Ramat Aviv, ,","place":["Tel Aviv-Yafo, Israel, 6997801"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Asaf","family":"Nitsan","sequence":"additional","affiliation":[{"name":"Tel Aviv University , , P.O.B 39040, Ramat Aviv, ,","place":["Tel Aviv-Yafo, Israel, 6997801"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Or","family":"Messer","sequence":"additional","affiliation":[{"name":"Tel Aviv University , , P.O.B 39040, Ramat Aviv, ,","place":["Tel Aviv-Yafo, Israel, 6997801"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alexander","family":"Upcher","sequence":"additional","affiliation":[{"name":"Ben-Gurion University of the Negev , , P.O.B 653, ,","place":["Beer-Sheva, Israel, 8410501"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vladimir","family":"Ezersky","sequence":"additional","affiliation":[{"name":"Ben-Gurion University of the Negev , , P.O.B 653, ,","place":["Beer-Sheva, Israel, 8410501"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nitzan","family":"Maman","sequence":"additional","affiliation":[{"name":"Ben-Gurion University of the Negev , , P.O.B 653, ,","place":["Beer-Sheva, Israel, 8410501"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0242-1282","authenticated-orcid":true,"given":"Barak","family":"Ratzker","sequence":"additional","affiliation":[{"name":"Tel Aviv University , , P.O.B 39040, Ramat Aviv, ,","place":["Tel Aviv-Yafo, Israel, 6997801"]},{"name":"Max Planck Institute for Sustainable Materials , Max-Planck-Str. 1 , ,","place":["Du\u0308sseldorf, Germany, 40237"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8588-0585","authenticated-orcid":true,"given":"Maxim","family":"Sokol","sequence":"additional","affiliation":[{"name":"Tel Aviv University , , P.O.B 39040, Ramat Aviv, ,","place":["Tel Aviv-Yafo, Israel, 6997801"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2026,7,29]]},"reference":[{"issue":"26","key":"2026081110152856000_cit1","doi-asserted-by":"publisher","first-page":"2200574","DOI":"10.1002\/adma.202200574","article-title":"Transition Metal Carbo-Chalcogenide\n\u201cTMCC:\u201d A New Family of 2D Materials","volume":"34","author":"Majed","year":"2022","journal-title":"Adv.
