Synthesis, spectra and crystal structure of a novel 18-metallacrown-6 [Mn6(4-ohashz)6(CH3OH)6] · 12CH3OH

A new macrocyclic manganese(III) 18-azametallacrown-6 compound with the formula of [Mn6(4-ohashz)6(CH3OH)6] · 12CH3OH (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 Λ/Δ 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.
