摘要
The nickel(II) and silver(I) complexes [Ni(L1)ClO4]ClO4 and [Ag(L1)]ClO4 Of the 17-membered dibenzo macrocyclic ligand L1 with an N2S3 donor atom set have been prepared and characterized by X-ray crystal structure determinations. Nickel(II) is octahedrally coordinated by the five donor atoms of L1 and a perchlorate oxygen atom. The overall symmetry of the [Ni(L1)]2+ Moiety is close to m symmetry. In [Ag(L1)]+, all five donor atoms of the ligand are bound to the metal ion. The coordination polyhedron is best described as a distorted pentagonal bipyramid. The conformation of this and of related ligands within their -HN-(CH2)2-X-(CH2)2-NH- fragments (X = O, N or S) will be discussed.
