title: Bis[mu-3[5]-(2-pyridyl)pyrazolido]bis[(acetonitrile)copper(II)] diperchlorate.
abstract: The title compound, [Cu(2)(C(8)H(6)N(3))(2)(C(2)H(3)N)(2)](ClO(4))(2), contains a centrosymmetric dinuclear dication, with square-pyramidal Cu(II) centres linked by two 1,2-pyrazolide bridging groups. There is a weak apical interaction between each Cu ion and a perchlorate O atom.
