摘要

The structure of the tetrapolyphosphate Cr2P4O13 was determined from single-crystal X-ray diffraction data. It crystallizes in the monoclinic space group P21 c with a = 8.097(2), b = 8.787(3), c = 13.098(4)Å, β = 105.54(2)°, V = 897.8(5) Å3, Z = 4, and R = 0.0297, Rw = 0.0287 for 1802 unique reflections. Hexagonal tunnels along the a-axis are formed by the edges of two CrO6 octahedra and four PO4 tetrahedra. The framework consists of pairs of edge-sharing CrO6 octahedra forming Cr2O10 units and unusual tetrapolyphosphate anions P4O6-13. The phosphate anion forms a "U" shape and is built up by four corner-sharing PO4 tetrahedra. The present state of tetrapolyphosphate chemistry is briefly reviewed.
