合成了金属异核配合物{[GdCu (NTA ) (H2 O ) 6 Cl]ClO4·H2 O}n,通过单晶衍射测定其结构。配合物的晶体属三斜晶系 ,空间群P 1 ,a =0 84 830 ( 1 0 )nm ,b =0 9642 ( 2 )nm ,c =1 2 838( 2 )nm ,α =1 1 1 1 70( 1 0 )° ,β =93 52 0 ( 1 0 )°,γ =1 0 0 890 ( 1 0 )°,V =0 9530 ( 3)nm3,Z =2 ,Dc=2 335g·cm- 3。配合物的晶体呈现锯齿状一维链状结构。铜离子是五配位 ,配位多面体是一个扭曲四棱锥。每个NTA通过其氮原子和 3个羧基的 3个氧原子与铜离子螯合 ,形成 3个五元环 ,氯离子也与铜离子配位。ClO- 4作为平衡离子位于链间。
The metal heteronuclear complex {[GdCu (NTA) (H2 O) 6 Cl] ClO4 · H 2 O} n was synthesized and its structure was determined by single crystal diffraction. The crystal of the complex belongs to triclinic system, the space group P 1, a = 0 84 830 (1 0) nm, b = 0 9642 (2) nm, c = 1 2 838 (2) nm, α = 1 1 1 1 70 0 0 °, β = 93 52 0 1 0 °, γ = 1 0 0 890 1 0 °, V 0 9530 3 nm 3, Z 2, Dc 2 335 g · cm - 3. The crystal of the complex appears serrated one-dimensional chain structure. Copper ions are five-coordinated, coordination polyhedron is a twisted quadrangular pyramid. Each NTA chelates copper ions through its three nitrogen atoms and three oxygen atoms of the carboxyl group to form three five-membered rings, and chloride ions also coordinate to copper ions. ClO-4 is located as a counterion between the chains.
