✦ Synopsis

Compounds of general formula M(bdhe)C104 (M = Mn, Fe, Co, Ni, Cu, Zn) are formed by reaction between the tripod-like ligand NN-bis(2-diethylaminoethyl)-2-hydroxyethylamine (bdhe) and metal diperchlorate in acetone. Conductometric, spectroscopic and X-ray diffraction data indicate that all these compounds contain dinuclear high-spin fivecoordinate Mz(bdhe):' cations. Variable temperature (80-290 K) magnetic susceptibility data show the existence of a large antiferromagnetic exchange interaction for the copper(H) complex; weak antiferromagnetic interactions have been also observed for the cobalt(II) and nickel(II) derivatives.
