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ZnO_4四面体。具有近似的T_d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。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)nm^3. 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.
