摘要
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 [NaCr(8)B(4)P(12)O(60)H(8)](15-), which are built from [Cr(4)O(18)] groups, [BP(2)O(10)] anions and PO(4) tetrahedra with Na(+) cations encapsulated in the clusters. Magnetic investigation showed strong antiferromagnetic interactions between Cr(3+)-Cr(3+) dimers at low temperature.
