title: Synthesis and characterization of non-bridging mono- and bis-σ-η(1)-alkynyl derivatives of the phosphido-bridged hexaplatinum core [Pt6(μ-PBu(t)2)4(CO)4](2+).
abstract: Several mono- or bis-alkynyl derivatives of general formula Pt6(μ-PBu(t)2)4(CO)4X(C[triple bond, length as m-dash]C-R), Pt6(μ-PBu(t)2)4(CO)4(C[triple bond, length as m-dash]C-R)2 or Pt6(μ-PBu(t)2)4(CO)4(C[triple bond, length as m-dash]C-R)(C[triple bond, length as m-dash]C-R') were obtained under Sonogashira type conditions. The new clusters have been characterized with microanalysis and using IR and multinuclear NMR spectroscopy. The crystal and molecular structures of Pt6(μ-PBu(t)2)4(CO)4(C[triple bond, length as m-dash]C-R)2 (R = H, C6H4-4-n-C5H11) are presented and electrochemical and spectroelectrochemical studies of some representative compounds are also reported.
