Bimetallic Pt(II)-bipyridyl-diacetylide/Ln(III) tris-diketonate adducts based on a combination of coordinate bonding and hydrogen bonding between the metal fragments: Syntheses, structures and photophysical properties

Journal article

The luminescent Pt(II) complex [Pt(4,4′-tBu2-bipy){CC-(5-pyrimidinyl)}2] (1) was prepared by coupling of [Pt(4,4′-tBu2-bipy)Cl2] with 5-ethynyl-pyrimidine, and contains two pyrimidinyl units pendant from a Pt(II) bipyridyl diacetylide core; it shows luminescence at 520 nm which is typical of Pt(II) luminophores of this type. Reaction with [Ln(hfac)3(H2O)2] (hfac = anion of hexafluoroacetylacetone) affords as crystalline solids the compounds [1 · {Ln(hfac)3(H2O)}{Ln(hfac)3(H2O)2}] (Ln = Nd, Gd...
