Synthesis and characterization of Ru2(η2-DmAniF)2(μ-DmAniF)2(μ-OAc)(μ-0)

A new diruthenium compound, Ru-2(eta(2)-DmAniF)(2)(mu-DmAniF)(2)(OAc)(O) (1), where DmAniF is N,N'-di(m-methoxyphenyl)formamidinate, was isolated as a secondary product from the reaction between Ru-2(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 = 308 cm(-1)) as revealed by the measurement of temperature dependent magnetism. (C) 2015 Elsevier Ltd.
