Synthesis and characterization of Ru2(η2-DmAniF)2(μ-DmAniF)2(μ-OAc)(μ-O)

Abstract

A new diruthenium compound, Ru2(η2-DmAniF)2(μ-DmAniF)2(OAc)(O) (1), where DmAniF is N,N′-di(m-methoxyphenyl)formamidinate, was isolated as a secondary product from the reaction between Ru2(DmAniF)3(OAc)Cl and K2CO3, and its formulation was established using both single crystal X-ray diffraction and high resolution mass-spectrometry techniques. Compound 1 has an S=3/2 ground state, and exhibits an unusually large zero-field splitting (D=308cm−1) as revealed by the measurement of temperature dependent magnetism.
