Abstract
Three new binuclear copper(I) complexes, [Cu2(paa)(dppm)2](BF4)2 (1), [Cu2(N^N^O)(dppm)2]BF4 (2), and [Cu2(N^C^N)(dppm)2](BF4)2 (3), were prepared with bridging or chelating pyridine-2-carbaldehyde azine (paa or N^N-N^N), 2,4-dimethyl-7-hydroxyl-1,8-naphthyridine (N^N^OH), 1-methyl-3,5-di(2-pyridyl)benzene (N^C^N), and bis(diphenylphosphino)methane (dppm) ligands and their structures were determined by X-ray crystal analysis. The structural analysis revealed that coppers in the complexes are three- and four-coordinate and N^N-N^N adopts N,N chelating and bridging coordination modes while N^N^OH, N^C^N and dppm afforded only a bridging model. The two metal centers approach closely with copper(I)–copper(I) distances of 2.7811–3.420 Å. Intense solid-state emission centered at 490 nm was observed for 1.
