Abstract
A new polyoxoniobate with NbIVO8 center and Cu24 core K12Na[H23NbIVO8Cu24(Nb7O22)8]·81H2O (1) has been synthesized by the reaction of K7HNb6O19·13H2O with Cu(CH3COO)2·H2O in the presence of NbIVO2, and characterized by elemental analyses, IR spectrum, TG analysis, magnetic property and single-crystal X-ray diffraction. The structure analysis reveals that the polyoxoanion is composed of one NbIVO8 cube-like unit, 24 copper centers and eight [Nb7O22]9− fragments. The magnetic investigation shows that compound 1 exhibits antiferromagnetic interactions.
