We recently described the release of P<jats:sub>2<\/jats:sub> units from the nickel butterfly complex [{(IMes)Ni(CO)}<jats:sub>2<\/jats:sub>(\u03bc<jats:sup>2<\/jats:sup>,\u03b7<jats:sup>2<\/jats:sup>:\u03b7<jats:sup>2<\/jats:sup>\u2010P<jats:sub>2<\/jats:sub>)] (IMes=1,3\u2010bis(2,4,6\u2010trimethylphenyl)imidazolin\u20102\u2010ylidene) upon addition of CO gas. Herein, we developed an alternative protocol for the same process using heterocumulenes. In addition to formation of P<jats:sub>4<\/jats:sub> (the dimerisation product of P<jats:sub>2<\/jats:sub>), the reactions afford nickel complexes of novel pincer\u2010type ligands. Aryl isothiocyanates undergo a trimerisation within the coordination sphere of nickel and afford square planar nickel complexes with S\u2212C\u2212S pincer\u2010ligand frameworks. Carbon disulfide coordinates to the [(IMes)Ni]\u2010fragment in an \u03b7<jats:sup>2<\/jats:sup>\u2010fashion, affording a dinuclear complex. Similar products are formed when the N\u2010heterocyclic carbene nickel(0) complex [(IMes)Ni(vtms)<jats:sub>2<\/jats:sub>] is used as a precursor (vtms=vinyltrimethylsilane).<\/jats:p>","DOI":"10.1002\/ejic.202101057","type":"journal-article","created":{"date-parts":[[2022,2,14]],"date-time":"2022-02-14T22:49:36Z","timestamp":1644878976000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Diphosphorus Release and Heterocumulene Oligomerisation by Nickel Complexes"],"prefix":"10.1002","volume":"2022","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4029-3712","authenticated-orcid":false,"given":"Gabriele","family":"Hierlmeier","sequence":"first","affiliation":[{"name":"Universit\u00e4t Regensburg Institut f\u00fcr Anorganische Chemie  93040 Regensburg Germany"},{"name":"Princeton University Department of Chemistry  Frick Laboratory 206 Princeton NJ 08544 USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4066-6483","authenticated-orcid":false,"given":"Robert","family":"Wolf","sequence":"additional","affiliation":[{"name":"Universit\u00e4t Regensburg Institut f\u00fcr Anorganische Chemie  93040 Regensburg Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2022,3,14]]},"reference":[{"key":"e_1_2_8_1_1","doi-asserted-by":"publisher","DOI":"10.1002\/anie.197502321"},{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1126\/science.1102209"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/ejic.201201368"},{"key":"e_1_2_8_4_1","unstructured":"\u00a0"},{"key":"e_1_2_8_5_2","doi-asserted-by":"publisher","DOI":"10.1002\/anie.198505221"},{"key":"e_1_2_8_6_2","doi-asserted-by":"publisher","DOI":"10.1039\/a606262h"},{"key":"e_1_2_8_7_2","author":"Goh L.
