摘要：

Single crystals of alpha-KZnPO4, the low-temperature modification of potassium zinc orthophosphate, were obtained from KZnPO4 powder by high pressure experiments in a modified Belt-type apparatus. The crystals are hexagonal, space group P6(3), with a = 18.155(2), c = 8.504(1) angstrom, c/a = 0.4684 and Z = 24. The crystal structure, refined from diffractometer data to R = 0.077, R(w) = 0.068, comprises an ordered network of ZnO4 and PO4 tetrahedra with rings of six tetrahedra vertical to the c-axis. The potassium ions are located in cavities formed by the rings.
