A novel polyoxochromium borophosphate with new 6-membered ring crown-shaped clusters

Abstract

A novel chromium borophosphate with anionic clusters has been synthesized using boric acid as flux. X-ray diffraction analysis on a single crystal reveals that its structure comprises of crown-shaped 6-membered ring clusters [NaCr8B4P12O60H8]15−, which are built from [Cr4O18] groups, [BP2O10] anions and PO4 tetrahedra with Na+ cations encapsulated in the clusters. Magnetic investigation showed strong antiferromagnetic interactions between Cr3+–Cr3+ dimers at low temperature.
