Synthesis,spectra and crystal structure of a novel 18-metallacrown-6 [Mn_6(4-ohashz)_6(CH_3OH)_6]centre dot12CH_3OH

摘要

A new macrocyclic manganese(III) 18-azametallacrown-6 compound with the formula of [Mn_6(4-ohashz)_6(CH_3OH)_6]centre dot12-CH_3OH (4-ohashz=N-acetyl-(4-hydroxysalicylhydrazidate)) was synthesized and characterized.In this complex,the metal ion is forcing the stereochemistry of the ligands arranged into a propeller shape with alternating LAMBDA/DELTA configurations.The disc-shaped hexanuclear complex has a cavity in the center with a dimension of 8.69' in diameter and 3.13' in thickness and aligned approximately along the crystallographic c-axis,one-dimensional channels are formed.
