(Benzoylacetonato-O,O')(2,2'-bipyridine-N,N')(nitrato-O)copper(II)

The Cu^II atom in the title complex, (2,2'-bipyridine-N,N')(nitrato-O)(1-phenyl-1,3-butanedionato-O,O')copper(II), [Cu(C₁₀H₉O₂)(NO₃)(C₁₀H₈N₂)], has a square-pyramidal coordination. Both the benzoylacetone anion and the 2,2'-bipyridine ligand chelate to the Cu^II atom in the equatorial plane, while a nitrate anion occupies the apical site, with a longer Cu-O distance of 2.335 (4) Å. Within the delocalized enol ring of benzoylacetone, the C-C bond closest to the phenyl ring is longer than the C-C bond farthest from the phenyl ring.
