Abstract

Dinuclear complexes [M~2~(μ‐BPNNAn)]X~2~ (M = Cu^I^, X = ClO~4~^–^ 1, X = BF~4~^–^ 2; M = Ag^I^, X = BF~4~^–^ 3, X = ClO~4~^–^ 4) have been prepared by treating 9,10‐bis{[6‐(diphenylphosphanyl)‐2‐pyridylmethyl]propylaminomethyl}anthracene (BPNNAn) with M(CH~3~CN)~4~X in CH~2~Cl~2~. The structures of complexes 1, 2 and 3 have been determined by single‐crystal X‐ray diffraction studies. In the complexes, BPNNAn acts as a chelating ligand and two metal ions riding on two bridgehead carbon atoms in the anthracene group leads to the deformation of the anthracenyl ring. The Cu–Arene charge transfer interaction is observed from the nonfluorescent emission of Cu complex 1, while the Ag complex 3 exhibits dual emission at high concentrations in a CH~2~Cl~2~ solution.
