O-O,O')(2,2'-BIPYRIDINE-N,N')(NITRATO-O)COPPER(II)

The Cu-II atom in the title complex, ato-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 li gand chelate to the Cu-II atom in the equatorial plane, while a nitrat e anion occupies the apical site, with a longer Cu-O distance of 2.335 (4) Angstrom. Within the delocalized enol ring of benzoylacetone, the C-C bond closest to the phenyl ring is longer than the C-C bond farth est from the phenyl ring.
