Abstract: The title compound, [Cu(ClO₄)₂(C₆H₆N₂O₂)₂], contains neutral molecules of a centrosymmetric mononuclear copper(II) complex, in which the zwitterionic hydroxamic acid ligand is O,O'-chelated to the Cu^II atom. The Cu^II atom lies on an inversion centre and has a distorted tetragonal-bipyramidal environment, being coordinated by four O atoms of the two N-hydroxynicotinamide molecules forming the equatorial plane, and by two O atoms of the perchlorate anions occupying the axial positions.
