摘要： 通过水热法合成了一个新化合物[C6N2H18]2[Mo5O15(HPO4)2]·H2O,并通过IR光谱、ICP、元素分析、差热与热重分析和X射线单晶衍射分析等手段进行了表征.结果表明,晶体属三方晶系,P3(2)21空间群,a=1.1231(1)nm,c=2.2802(5)nm,V=2.4911(7)nm3,Dx=2.835Mg/m3,Z=6,最后的一致性因子R=0.0227,wR=0.0675.阴离子中Mo5O15构成一环状结构,2个HPO4一个连在环的下方,一个连在环的上方,形成类似于“飞碟”状的结构,阳离子为2个质子化的四甲基乙二胺.

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.
