Abstract

Conditions were found for the synthesis of new trinuclear carboxylates [M3O(CH3COO)6(pz)3]+ (M = Fe, Cr; pz = pyrazine). The composition of the obtained complexes was established on the basis of elemental analysis, mass spectrometry, and electronic and IR spectroscopy. It was shown that the substitution of water molecules by pyrazine leads to some increase in the antiferromagnetic exchange between the metal ions of the trinuclear cation. It was established that spin frustration exists in the complexes.
