摘要
Introduction The substitution of atom N for O in macrocyclic crown ether greatly influences its complexation. It is just expected that the complexing effects of the substituted macrocyclic on transition metals are greatly increased. The present paper covers the synthesis, structure and characterization of the complex [MnL（NCS）;] of title macrocyclic ligand (L is 1-oxa-4, 7, 10-triazacy-
