Herein, we report a new high-yielding synthesis of 2 and the isolation of its new polymorph (2\u2019). In addition, we study its reactivity towards AgI and CuI ions. The reaction of 2 with Ag[BF4] selectively produces the coordination compound [Ag{Cp*Fe(\u00b5,\u03b75:\u03b75-P5)Mo(CO)3}2][BF4] (3). Its reaction with Ag[TEF] and Cu[TEF] ([TEF]\u2212 = [Al{OC(CF3)3}4]\u2212) leads to the selective formation of the complexes [Ag{Cp*Fe(\u00b5,\u03b75:\u03b75-P5)Mo(CO)3}2][TEF] (4) and [Cu{Cp*Fe(\u00b5,\u03b75:\u03b75-P5)Mo(CO)3}2][TEF] (5), respectively. The X-ray structures of compounds 3\u20135 each show an MI ion (MI = AgI, CuI) bridged by two P atoms from two triple-decker complexes (2). Additionally, four short MI\u00b7\u00b7\u00b7CO distances (two to each triple-decker complex 2) participate in stabilizing the coordination sphere of the MI ion. Evidently, the X-ray structure for compound 3 shows a weak interaction of the AgI ion with one fluorine atom of the counterion [BF4]\u2212. Such an Ag\u00b7\u00b7\u00b7F interaction does not exist for compound 4. These findings demonstrate the possibility of using triple-decker complex 2 as a ligand in coordination chemistry and opening a new perspective in the field of supramolecular chemistry of transition metal compounds with phosphorus-rich complexes.<\/jats:p>","DOI":"10.3390\/molecules24020325","type":"journal-article","created":{"date-parts":[[2019,1,17]],"date-time":"2019-01-17T11:30:27Z","timestamp":1547724627000},"page":"325","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["The Triple-Decker Complex [Cp*Fe(\u00b5,\u03b75:\u03b75-P5)Mo(CO)3] as a Building Block in Coordination Chemistry"],"prefix":"10.3390","volume":"24","author":[{"given":"Mehdi","family":"Elsayed Moussa","sequence":"first","affiliation":[{"name":"Department of Inorganic Chemistry, University of Regensburg, 93040 Regensburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stefan","family":"Welsch","sequence":"additional","affiliation":[{"name":"Department of Inorganic Chemistry, University of Regensburg, 93040 Regensburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Luis","family":"D\u00fctsch","sequence":"additional","affiliation":[{"name":"Department of Inorganic Chemistry, University of Regensburg, 93040 Regensburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Martin","family":"Piesch","sequence":"additional","affiliation":[{"name":"Department of Inorganic Chemistry, University of Regensburg, 93040 Regensburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stephan","family":"Reichl","sequence":"additional","affiliation":[{"name":"Department of Inorganic Chemistry, University of Regensburg, 93040 Regensburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael","family":"Seidl","sequence":"additional","affiliation":[{"name":"Department of Inorganic Chemistry, University of Regensburg, 93040 Regensburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2182-5020","authenticated-orcid":false,"given":"Manfred","family":"Scheer","sequence":"additional","affiliation":[{"name":"Department of Inorganic Chemistry, University of Regensburg, 93040 Regensburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,1,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"114","DOI":"10.1016\/j.ccr.2018.06.012","article-title":"Transition metal complexes of the naked pnictide elements","volume":"376","author":"Whitmire","year":"2018","journal-title":"Coord.
