摘要：

Two new quinquedentate pentaazamacrocycles, 7-(2'-pyridylmethyl)-3,7,11,17-tetraazabicyclo-[11.3.1]heptadeca-1(17),13,15-tr iene L1 and its 3,11-dimethyl derivative L2, have been characterised, together with their metal complexes of formulae [ML(OH2)] [BF4]2 (M = Ni or Cu) and [ZnL] [BF4]2 (L = L1 or L2) . The crystal structure of [ZnL1][BF4]2 shows a distorted square-pyramidal geometry, with the Zn 0.59 angstrom above the plane of the macrocyclic ring in the direction of the pendant co-ordinated pyridyl group.
