Direct synthesis of an heterometallic {MnII3CrIII4} wheel by decomposition of Reineckes salt

Abstract

A new heterometallic Mn/Cr molecular wheel complex has been synthesized using zerovalent manganese, Reineckes salt, ammonium thiocyanate and triethanolamine (H3tea) as starting materials. The compound [Mn3Cr4(NCS)6(Htea)6] (1) has been characterized in terms of its electrochemical, IR and EPR spectroscopic as well as its magnetic properties. The magnetic susceptibility and magnetization data were treated simultaneously during the optimization routine and resulted in JMn–Cr = +0.43 cm−1, JCr–Cr = −4.75 cm−1, JMn–Mn = +1.78 cm−1, geff = 1.878 with the ground state S = 15/2.
