Electrochemical synthesis and crystal structure of a penta-coordinated silver(II) macrocyclic complex

We present the electrochemical synthesis by galvanostatic electro-oxidation method and single crystal structure determination of a complex of silver(II) with a macrocyclic N donor ligand crystallized with hexafluorophosphate anions. The crystal structure analysis showed a penta-coordinated environment of silver(II) and displacement of the metal centre from the rectangular planar configuration of the macrocyclic N donor which is due to axial coordination by a solvent acetonitrile molecule. Both PF₆⁻ anions were modelled with two-fold disorder.
