Synthesis, NMR characterisation and crystal structure of the silver(I) annular complex [Ag2(μ-ppye )2] [PF6]2·2(CH3)2CO (ppye=1-(diphenylphosphino)-2-(2-pyridyl)ethane)

The silver(I) complex [Ag2(μ-ppye)2] [PF6]2·2(CH3)2CO (ppye=1-(diphenylphosphino)-2-(2-pyridyl)ethane) has been prepared and its crystal structure determined by single-crystal X-ray diffraction. The dication [Ag2(μ-ppye)2]2+ exhibits a twelve-membered annular core structure with ppye ligands bridging head-to-tail the silver ions, which lie in a distorted linear environment. Each Ag(I) centre shows also a weak electrostatic interaction with the oxygen atom of an acetone molecule (Ag...O=2.86(1) A), which is probably responsible for the deviation from linearity of the P - Ag - N angle (165.8(1)°). The size of the cavity can be estimated on the basis of the Ag...Ag distance, 5.077(1) A. Crystallographic data: monoclinic, space group P21/n, a = 13.330(1), b = 13.469(1), c = 14.102(2) A, β = 103.02(5)°, U = 2466.7(6) A3, Z=2, R=0.071. The dynamic behaviour of the complex in acetone solution has been investigated by means of variable-temperature multinuclear (1H, 13C and 31P) NMR spectroscopy.
