摘要： 本文作者制得的单品经分析证明是由质子化大环LH4+4阳离子、Co(NCS)6-4阴离子、一分子Co(NO3)2和4分子H2O组成,还证明质子化大环L以船式构象存在,为研究超分子配合物的催化机理提供了结构依据。本实验还发现六异硫氰根合钴(Ⅱ)配阴离子能稳定存在。

Abstract: Anew complex of protonated 24-membered hexaaza-dioxa macrocycle LH44+ with hex-aisothiocyanatocobalt( Ⅱ ) was synthesized and the crystal structure of [C16H42N6O2][Co(NCS)6] · Co (NO3)2 · 4H2O was determined. It crystallizes in the triclinic system, space group P1(a = 7. 992(1)Å, 6=11. 007(2)Å, c-=27. 328(2)Å, a = 79. 01(2)°, β=81. 57(2)°, γ= 68. 70(2)°, V = 2190. 9Å3, Z=2). The protonated macrocycle L in the complex is in a boat type conformation. Comparing IR and NMR of the free protonated macrocycle L with those of the macrocycle L in the complex, it is proved that the conformation of the free protonated macrocycle L is the same as that of the macrocycle Lin the complex. The results obtained provide a basis for study of catalytic mechanism in supermolecule.The six-coordinated isothiocyanatocobalt complex anion [Co(NCS)6]-4 is rare in the literature. Its structure is octahedral.
