Abstract

Reaction of Mn(ClO4)2 with di-pyridyl ketone oxime, (2-py)2C[double bond, length as m-dash]NOH, gives the novel cluster [MnII4MnIII6MnIV2(μ4-O)2(μ3-O)4(μ3-OH)4(μ3-OCH3)2(pko)12](OH)(ClO4)3 1. It is the only example of a 24-MC-8, and the first metallacrown with ring metal ions in three different oxidation states. Magnetic measurements show antiferromagnetic behavior.
