Tetrakis(4-cyanopyridine)palladium(II) bis(trifluoromethanesulfonate)

Abstract

The title salt, [Pd(C6H4N2)4](CF3SO3)2, comprises Pd(4-cyano­pyridine)4 dications balanced by two trifluoro­methane­sulfonate anions. The PdII atom lies in a square-planar geometry defined by four N atoms which form equivalent Pd—N inter­actions. The 4-cyano­pyridine ligands are twisted out of the N4 plane, forming dihedral angles ranging from 66.5 (2) to 89.9 (2)°. In the crystal packing, columns of edge-to-edge dications define channels in which reside the anions. A range of C—H⋯N and C—H⋯O hydrogen-bonding interactions stabilizes the crystal packing.
