Single crystals of the compound α -Zn3(BO3)(PO4) were obtained at 1050 °C by using B2O3, P2O5 and ZnCO3 as starting materials and subsequent cooling to 600°C with 20°C/h. X-ray investigations on single crystals yield a new crystal structure in the monoclinic space group Cm - (Nr. 8) with a = 972.5(2); b = 1272.0(3); c = 487.4(3) pm; β = 119.80 (4)°; Z = 4. The structure contains isolated trigonally planar BO3 and tetrahedral PO4 units which are not joined together. Zinc occupies three crystallographically different point positions and is trigonal-bipyramidally, tetragonal-pyramidally or distorted tetrahedrally coordinated by oxygen
