Synthesis, Structure and Photoluminescence of [Cu(acac)(dppe)]n with Novel 1D Zigzag Chain-Like Motif

A novel complex [Cu(acac)(dppe)]n (1) [acac = acetylacetone; dppe = 1,2-bis(diphenylphosphino)ethane] was obtained by solution reactions and structurally characterized by X-ray diffraction. The crystal structure analysis indicates that the title complex is characteristic of a polymeric chain formed by the dppe ligands bridging neighboring copper centers. The copper atom is in a distorted tetrahedral geometry. Photoluminescent investigation reveals that the title complex displays a strong emission in bluelight regio
