摘要： 由四圆衍射仪收集标题化合物Zn(DMP)2的衍射数据。用直接法解出其单晶结构为:空间群Pc,a=0.9361(2),b=1.0519(3).c=1.2028(2)nm. β=91.01(2)°,Z=4.锌原子与4个配体的非酯氧原子形成ZnO4四面体。具有近似的Td对称性。相邻锌原子由“O-P-O”桥相连,形成一维链状配位聚合物。红外光谱证实O-P-O基的形成。对某些重要的谱带进行了解释,说明了Zn-O振动与配位阴离子振动的混合情况。

关键词: 双-(磷酸二甲酯)合锌, 晶体结构, 红外光谱

Abstract: The crystal of the title complex, is monoclinic with space group Pc. cell parameters a=0.9361(2),b=1.0519(3),c=1.2028(2)nm,β=91.01(2)?,V=1.1843(4)nm3. Z=4.final R=0.061.Zinc atom is coordinated in a tetrahedron arrangement to four non-esterified oxygen atoms.Two adjacent zinc atoms are connected by "O-P-O" bridge groups, forming an infinite one-dimensional chain coordinated polymer.The infrared spectra indicates formation of the O-P-S groups some important infrared bands have been interpreted.

Key words: bis-(dimethoxy phosphato) zinc, crystal structure, infrared spectra
