Abstract
Bis(o-aminobenzaldehyde)thiocarbohydrazone (HL) forms with copper(II) nitrate a tetranuclear complex [Cu2(L)(NO3)3]2·2H2O, in which two dinuclear units are joined by nitrate bridges. The dihydrazone ligand behaves ditopically, providing NNS and NNN binding sites, with the four coppers essentially in a square-pyramidal geometry. The tetranuclear molecule displays intramolecular magnetic interactions, with the antiferromagnetic exchange (−2J = 210(1) cm−1) between the copper(II) ions within each dinuclear moiety dominant over weak interdimer ferromagnetic coupling.
