Abstract

Chemistry Chemistry, Inorganic & Nuclear Physical Sciences Science & Technology
Bis(o-aminobenzaldehyde) thiocarbohydrazone (HL) forms with copper(II) nitrate a tetranuclear complex [Cu(2)(L)(NO(3))(3)](2)center dot 2H(2)O, 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.
