A heterometallic ferrimagnet based on a new TTF-bis(oxamato) ligand

Abstract

An oxamato unit has been introduced into a tetrathiafulvalene (TTF) system for the first time via direct condensation, generating a new π-extended TTF ligand, TTF-Et2H2opba (opba = ortho-phenylenebis-oxamato). On the basis of this ligand, the Cu(II) complex [(n-Bu)4N]2[Cu(TTF-opba)] (1) has been obtained. By employing this complex as a “metalloligand”, we have successfully prepared an interesting heterometallic one-dimensional complex {[Cu(TTF-opba)][Mn(CH3OH)2]}n (2), via coordination of the free carbonyl-oxygen atoms of the two oxamato groups with Mn(II) ions. The new compounds have been structurally characterized, and their electrochemical and magnetic properties probed. Complex 2 shows a ferrimagnetic behavior with g = 1.96 and J = −22.36 cm−1.
