本文报道二价铜与叠氮、大环穴醚(C_(16)H_(38)N_6)配合物的合成和晶体结构.配合物组成为[Cu_2(N_2)_2(C_(16)H_(38)N_3)](ClO_4)_2,晶体属于空间群C_1~1-PI,晶胞参数a=17.669(10).b=13.355(5),c=6.414(3)A;β=103.85(4),β=100.40(4),γ=71.30(3)°;对1870个反射精修的最后一致性因子R=0.088.此配合物中Cu(Ⅱ)呈平面正方四配位结构形式,这在类似饱和大环穴醚双铜配合物中,还是首次发现.每个配位多面体由大环穴醚配体提供三个氮原子,叠氮离子提供一个氮原子,两个Cu(Ⅱ)离子之间不存在叠氮桥,间距为5.12A.
In this paper, the synthesis and crystal structure of complexes of Cu (Ⅱ) with azide and macrocyclic ether (C_ (16) H_ (38) N_6) ) C (3) A; β = 103.85 (4). The crystal belongs to the space group C_1 ~ 1-PI and the unit cell parameters a = 17.669 (10) .b = 13.355 , β = 100.40 (4), γ = 71.30 (3) °, and the final concordance factor R = 0.088 for 1870 Refined Reflections.The Cu (Ⅱ) It is also the first time to find that the coordination polyhedron provides three nitrogen atoms from the macrocyclic ether ligand and azide ions provide one nitrogen atom and two Cu (II) ions Azide bridge does not exist between the spacing of 5.12A.
