The cluster is formed by two (µ3-OH) and two (µ2-OH) units that bond platinum atoms in different oxidation states. The cluster core geometry can best be described as a half-hexagram. Compound 1 is an excellent precursor for preparing heterometallic clusters since it can host d10 or s2 Lewis-acid metal centers through Pt¿M dative bonds, as demonstrated by its reaction with Ag(i) to produce the heterometallic [Ag2PtIVPtII3(C6Cl5)8(µ2-OH)2(µ3-OH)2] (2), which has four unbridged Pt-Ag bonds.2017http://zaguan.unizar.es/record/16824010.1039/c7cc07712bhttp://zaguan.unizar.es/record/168240oai:zaguan.unizar.es:168240info:eu-repo/grantAgreement/ES/DGA/E21info:eu-repo/grantAgreement/ES/MCIU/MAT2015-68200-C2-1-Pinfo:eu-repo/grantAgreement/ES/MINECO/CTQ2015-67461-PChemical Communications 53, 98 (2017), 13121-13124All rights reservedhttp://www.europeana.eu/rights/rr-f/info:eu-repo/semantics/openAccess
