Abstract: C6N2H 18]2[Mo5O 15(HPO4)2]·H2O has been obtained by using hydrothermal synthesis, and the results of X-ray single crystal diffraction show that the compound crystalliized in space group {P3(2)21} of trigonal system with a=1.123 1(1) nm, c=2.280 2(5) nm, V=2.491 1(7) nm3, Dx=2^835 {Mg/m3}, Z=6 and R=0.022 7, wR=0.067 5. The crystal structure of [C6N2H 18]2[Mo5O 15(HPO4)2]·H2O is composed of two protoned tertramethyldiamine, [C6N2H 18] 4+2, [Mo5O 15(HPO4)2] 4- and one molecule water. In the anion H2Mo5P2O 4- 23, five octahedral MoO6 are connected by sharing-angle to form a pentagon and three oxygen atoms of two PO4 tetrahedral is connected to five Mo atoms. Five octahedral MoO6 and two PO4 tetrahedral are connected to form this anion like flying saucer.
