title: Tetra-kis(4-cyano-pyridine)-palladium(II) bis-(trifluoro-methane-sulfonate).
abstract: The title salt, [Pd(C(6)H(4)N(2))(4)](CF(3)SO(3))(2), comprises Pd(4-cyano-pyridine)(4) dications balanced by two trifluoro-methane-sulfonate anions. The Pd(II) atom lies in a square-planar geometry defined by four N atoms which form equivalent Pd-N inter-actions. The 4-cyano-pyridine ligands are twisted out of the N(4) 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.
