摘要
测定了CaPHT·H_2O和两种CaPHT的晶体结构,其空间群分别属于P2_1/c(C_(2h)~5,Z=4),P2_1/m(C_(2h)~2,Z=8)和 P2/m(C_(2h)~1,Z=6).研究了 CaPHT·H_2O、CaPHT(A)、CaPHT(B)、MgPHT、SrPHT 和 BaPHT 的 IR 及 CaPHT·H_2O 的拉曼光谱,讨论了固体样品中 PHT 与碱土金属离子的配位结构及其对光谱的影响.
The crystal structures of Ca(C_8H_4O_4)·H_2O and two types of Ca(C_8H_4O_4) have beenmeasured.The space groups are P2_1/c (C_(2h)~5,Z-4),P2_1/m(C_(2h)~2,Z=8) and P2/m (C_2h^1,Z=6),respectively.The IR spectra of Ca(C_8H_4O4)·H_2O and M(C_8H_4O_4)(M=Mg,Ca,Sr,and Ba) as well as the Raman spectrum of Ca(C_8H_4O_4)·H_2O have been investigated.The coordinate structures of phthalate groups with alkali-earth metal ions and theinfluence on spectra have been discussed.
