The dicopper(I) complex with 2-(diphenylphosphino)pyridine (Ph<SUB>2</SUB>Ppy), [Cu<SUB>2</SUB>(μ-Ph<SUB>2</SUB>Ppy)<SUB>2</SUB>(CH<SUB>3</SUB>CN)<SUB>2</SUB>](PF<SUB>6</SUB>)<SUB>2</SUB> has been prepared. The crystal structure has been determined crystallographically: Space group <I>P</I>\bar1, <I>a</I>=10,807(6), <I>b</I>=11.756(8), <I>c</I>=8.606(7) Å, α=90.36(6), β=95.98(5), γ=92.90(5)°, <I>Z</I>=1, <I>R</I>=0.067. The two copper atoms are bridged by two Ph<SUB>2</SUB>Ppy molecules in a head-to-tail arrangement, resulting in a rare staggered conformation of the eight-membered ring CU<SUB>2</SUB>P<SUB>2</SUB>N<SUB>2</SUB>C<SUB>2</SUB>, whose factor is concerned with the coordination numbers of the central metal atoms. <SUP>1</SUP>H NMR studies show that the ligand of a CH<SUB>3</SUB>CN in the titled compound undergoes dissociation in acetone solution.
