However, it is not known whether atoms in discrete molecules can undergo vacancy\u2010induced dynamics.

Variable\u2010temperature NMR analysis, X\u2010ray structure analysis, and theoretical calculations indicate that an atomic vacancy is located at the surface sites of the Pd\n                    <jats:sub>12<\/jats:sub>\n                    core, and that it migrates rapidly on the NMR timescale. This means that all 11 palladium atoms at the surface undergo self\u2010diffusion with a low energy barrier. These results demonstrate, for the first time, that atomic diffusion occurs within a molecule through the vacancy mechanism.\n                  <\/jats:p>","DOI":"10.1002\/anie.202507444","type":"journal-article","created":{"date-parts":[[2025,6,26]],"date-time":"2025-06-26T03:18:38Z","timestamp":1750907918000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Vacancy\u2010Induced Atomic Diffusion in a Molecular Metal Cluster Complex"],"prefix":"10.1002","volume":"64","author":[{"given":"Kosuke","family":"Iwata","sequence":"first","affiliation":[{"name":"Department of Chemical Science and Engineering School of Materials and Chemical Technology, Institute of Science Tokyo  O\u2010okayama Meguro\u2010ku Tokyo 152\u20108552 Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Koshi","family":"Miyazawa","sequence":"additional","affiliation":[{"name":"Department of Chemical Science and Engineering School of Materials and Chemical Technology, Institute of Science Tokyo  O\u2010okayama Meguro\u2010ku Tokyo 152\u20108552 Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kenta","family":"Kurashima","sequence":"additional","affiliation":[{"name":"Department of Chemical Science and Engineering School of Materials and Chemical Technology, Institute of Science Tokyo  O\u2010okayama Meguro\u2010ku Tokyo 152\u20108552 Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hiroshige","family":"Yamaura","sequence":"additional","affiliation":[{"name":"Department of Chemical Science and Engineering School of Materials and Chemical Technology, Institute of Science Tokyo  O\u2010okayama Meguro\u2010ku Tokyo 152\u20108552 Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bo","family":"Zhu","sequence":"additional","affiliation":[{"name":"Institute of Functional Materials Chemistry, Faculty of Chemistry Northeast Normal University  Changchun 130024 P.R.
