trans-Diaqua­{5,5'-[(E,E)-pyridine-2,6-diylbis(methyl­idynenitrilo)]bis­[pyrimi­dine-2,4(1H,3H)-dione]}zinc(II) nitrate hexa­fluorophosphate trihydrate

The title compound, [Zn(C₁₅H₁₁N₇O₄)(H₂O)₂](NO₃)(PF₆)·3H₂O, contains a mononuclear zinc(II) complex. The Zn²⁺ centre is seven-coordinated in a slightly distorted penta­gonal-bipyramidal geometry, with the two water O atoms located in the apical positions, and the pyridine N atom, the two imine N atoms and two carbonyl O atoms of the uracil groups located in the equatorial plane. The charge is balanced by PF₆^- and NO₃^- anions.
