Abstract
A complex of the formula [Cu-2(PEAH(2))(2)(NO3)(H2O)]-(N O-3) [PEAH(3) = 3,5-bis(N-ethylamido)pyrazole] was synthesized and its crystal stru cture determined by XRD methods. It consists of a dimeric cation with two bridging pyrazolate groups and a NO; anion. The geometries of the coordination polyhedra around the copper(II) ions are distorted square pyramidal. The variable temperature (20-300 K) magnetic susceptibilit y data gave the antiferromagnetic interaction constant as J = - 19l cm (-1), showing that the pyrazole molecule is very effective in transmit ting the exchange interaction.
