Universidad de Zaragoza (orcid)0000-0002-5881-9698 A route to small clusters: A twisted half-hexagram-shaped M4(OH)4 cluster and its capacity for hosting closed-shell metals 2017 Access copy available to the general public Unrestricted By combining different oxidation states, coordination indices and bridging systems, it has been possible to obtain the structurally novel M4(OH)4 cluster core (M = transition metal) found in the organometallic compound (NBu4)2[PtIVPtII3(C6Cl5)8(µ2-OH)2(µ3-OH)2] (1). 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. info:eu-repo/grantAgreement/ES/DGA/E21 info:eu-repo/grantAgreement/ES/MCIU/MAT2015-68200-C2-1-P info:eu-repo/grantAgreement/ES/MINECO/CTQ2015-67461-P info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 6.29 2017 CHEMISTRY, MULTIDISCIPLINARY 28 / 169 = 0.166 2017 Q1 T1 2.555 2017 Catalysis 2017 Q1 Ceramics and Composites 2017 Q1 Chemistry (miscellaneous) 2017 Q1 Surfaces, Coatings and Films 2017 Q1 Materials Chemistry 2017 Q1 Metals and Alloys 2017 Q1 Electronic, Optical and Magnetic Materials 2017 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Garciá-Monforte, M.A. Universidad de Zaragoza (orcid)0000-0001-7901-1420 González, R.
