摘要：

The high-pressure phase IV of potassium dihydrogen phosphate (KH2PO4, KDP) has been determined at 1.62 GPa/296 K. It is monoclinic, space group P2(1)/c, Z = 12, and on decompression transforms into monoclinic phase I. The interplay of OH center dot center dot center dot O bonding networks and K+ coordination types leads to an exceptionally large number of KDP polymorphs, at least 13 according to the literature.
