title: Bis[3-ethyl-4-(4-methoxy-phen-yl)-5-(2-pyrid-yl)-4H-1,2,4-triazole-κN,N]bis-(perchlorato-κO)copper(II) acetonitrile disolvate.
abstract: In the title compound, [Cu(ClO(4))(2)(C(16)H(16)N(4)O)(2)]·2CH(3)CN, the Cu(II) atom, located on an inversion center, is in a tetra-gonally distorted octa-hedral environment, coordinated by four N atoms of two bidentate 3-ethyl-4-(4-methoxy-phen-yl)-5-(2-pyrid-yl)-4H-1,2,4-triazole ligands in equatorial positions and by the O atoms of two perchlorate groups in axial positions. The long axial Cu-O bond of 2.4743 (17) Å is the result of the Jahn-Teller effect.
