In the title complex, {[Cu(SiF6)(C11H8N2O)2]·2H2O}n, the CuII atom adopts an N4F2-octa­hedral coordination geometry with four pyridine N atoms in the equatorial sites and two F atoms in the axial sites. The di-3-pyridyl­methanone and hexa­fluoro­silicate ligands act as bidentate ligands, linking symmetry-related CuII atoms. Water mol­ecules form O—H⋯O and O—H⋯F hydrogen bonds with the di-3-pyridyl­methanone and hexa­fluoro­silicate ligands. The Cu2+ and SiF62− ions are each located on a twofold axis.
