Abstract
The magnetic interaction between dinuclear copper (II) in a new copper carboxylate compound, STAM-1, has been investigated by means of EPR and SQUID measurements. The powder EPR spectra, measured at 9.80 and 34.5GHz and at different temperatures, show the typical lines of the triplet state (S=1), attributed to Cu2+–Cu2+ dimers, in addition of a temperature dependent central lines. The zero field splitting parameters obtained are |Dobs|=0.337cm−1 and E∼0. Magnetic susceptibility data, performed in the range 1.8–300K, shows a strong antiferromagnetic exchange coupling between the Cu2+ centers in the paddle-wheel units with the exchange coupling constant 2J=−334±4cm−1.
