摘要
用X射线单晶衍射法测定了三水合二(5-磺基水杨酸)钙(C(14)H1(10)O(12)S2Ca·3H2O,1)和二水合(5-磺基水杨酸)二钾(C7H4O6SK2·2H2O,2)的晶体结构·化合物1属单斜晶系,空间群为Pn。,晶胞参数a=5.604(1),B=18.560(4),c=10.006(2),β=102.19(3)°,Z=2,最终R=0.0244.化合物2属正交晶系,空间群Pbca,晶胞参数a=25.841(5),b=12.186(2),c=7.739(2),Z=8,最终R=0.0308.化合物1粉末倍频效应为2.86倍KH2PO4。
By means of the X-ray single crystal diffraction method, the crystal structures of cai-cium 5-suifosalicylate trihydrate (C14H10O12S2Ca.3H2O, 1) and potassium 5-sulfosalicylate dihy-drate (C7H4O6SK2·2H2O, 2) were dctcrndned- Compound 1 belongs to monochnic system, spacegroup is Pn, unit cell parametcr a=5. 604(1)A, b=18.560(4)A, c=10.006(2)A, D=102.19(3) ,V=1017.2(3)As, Z=2, dc=1.725g·cm-3, in the end R=0.0244. Compound 2 belongs to orthorhombic system, space group is Pbca, unit cell parameter a=25.841(5)A, b=12.186(2)A, c=7.739(2)A.V=2437.0(9)A2; Z=8, dc=1.801g.cm-3, in the end R=0.0308. The powder second harmonic generation(SHG) efficiency of compound 1 is as 2.86 times as that of KH2PO4. The ultravioletabsorption edge of its centimeter sizes single crystal is about 375nm.
