Abstract

The Cr₂(Sq)₂(OH)₂ · 6H₂O complex (Sq = squarate), synthesized by a hydrothermal method, was characterized by elemental analysis, i.r. and electronic reflection spectra. The variable-temperature magnetic susceptibility of the complex was measured over the 77-300 K range. The magnetic coupling parameter is consistent with an antiferromagnetic exchange model based on the Hamiltonian operator (Ĥ = -2JŜ₁Ŝ₂, where S₁ = S₂ = 3/2), giving the antiferromagnetic coupling parameter of 2J = -11.5 cm^-1.
