Abstract
In our attempts to identify new species in the preparation of copper(I)-Dppm (Dppm = bis(diphenylphosphino)methane) complexes under the condition of excess Dppm, we isolated and analyzed a new binuclear copper(I)-Dppm complex, namely, [(μ2-η1,η1-Dppm)2Cu2(η1-Dppm)2(μ2-Cl)](BF4) (I). We report here the synthesis, crystal structure (CIF file CCDC no. 1912269), characterizations by various spectroscopic (IR, 1HNMR, UV−Vis, powder XRD) techniques and the thermal and luminescent properties of this complex. Its X-ray crystal structure reveals a discrete cationic binuclear copper(I)-Dppm (1 : 2) species for the first time. The binuclear copper centres are bridged by a pair of cis-Dppm molecules and one chloride ion, and further consolidated by two trans-Dppm molecules in mono-dentate fashion. It exhibits cyan photoluminescence in the solid state at room temperature. This work not only addresses the concern of structural information of binuclear copper(I)-Dppm (1 : 2) complex, but also provides a new way to incorporate sterically hindered ligands into the {Cu(μ2-η1,η1-trans-Dppm)2Cu} scaffold for novel luminous properties.
