A heteroleptic Pt-doped Cu-rich hydrides nanocluster

An atomically precise heteroleptic Pt-doped Cu-rich hydride nanocluster [PtH2@Cu14(dtc)6(C2Ph)6] (PtH2Cu14-dtc) has been successfully synthesized. This was achieved by introducing a discrete Pt(II) precursor to the copper hydride nanocluster [Cu28H15(dtc)12](PF6) in the presence of terminal alkynes. The structure of PtH2Cu14 determined by X-ray diffraction reveals a bicapped icosahedral copper(I) cage encapsulating a linear platinum dihydride [PtH2]2- unit. The interstitial hydrides are arranged in a trigonal bipyramidal (tbp) geometry with a five-coordinated hydride as confirmed by 2H NMR and ESI-MS measurements.
