摘要
合成了苯并15-冠-5(B15-C-5)的配合物[Na(B15C5)·H2O]2[Zn(NCS)4],通过元素分析、红外光谱、X-射线单晶结构衍射对配合物进行了表征.该配合物为单斜晶系,空间群C2/C,晶体学结构数据:a=1.692 4(5)nm,b=1.299 8(4)nm,c=2.148 3(4)nm,β=112.352(6)°,V=4.371(2)nm3,Z=4,Dc=1.389mg/m3,F(000)=1896,R1=0.065 7,wR2=0.178 3.结构分析表明:Na+与B15-C-5分子中氧原子配位成键,阴离子为[Zn(NCS)4]2-具有四面体构型.两个[Na(B15C5)·H2O」+配阳离子与一个[Zn(NCS)4]2-配阴离子通过离子键形成中性配合物.
The Complex [Na(B15C5) · H2O]2 Zn(NCS)4 has been synthesized and characterized by elemental analysis,IR and X-ray diffraction analysis. The crystal belongs to monoclinic,space group C2/ C with cell dimensions,a = 1. 692 4(5),b=1. 299 8(4),c = 2.148 3(7) nm,β=112. 352(5)°,V = 4. 362(5) nm3,Z=4,Dc=1. 389 Mg · m-3,F(000) = 1 869,R1 = 0. 0657,wR2 = 0.178 3. Zn atom is coordinated by four N atoms and Zn(NCS)42- is terahedral structure. Na+ is coordinated by five atoms which come from one benzo-15-crow-5 molecule. Two [Na(B15C5). H2O]+ and one Zn(NCS)42- is formed neutral complex.
