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 structure of CaPHT · H_2O and two kinds of CaPHT were determined. The space group belongs to P2_1 / c (C_ (2h) ~ 5, Z = 4) The Raman spectra of CaPHT · H_2O, CaPHT (A), CaPHT (B), MgPHT, SrPHT and BaPHT and CaPHT · H_2O were studied. Coordination Structure of PHT with Alkaline Earth Metal Ions in Solid Samples and Its Effect on Spectra.
