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.
