Two different terminal nitrate bonding modes in [Fe2O(NO3)4(C7H7N3)4]
Abstract
Treatment of Fe(NO3)3·9H2O with 1-methylbenzotriazole in EtOH–CH(OEt)3 gave the unique, oxo-bridged complex [Fe2O(NO3)4(C7H7N3)4]; crystal structure and Mössbauer studies showed that the molecule has both bidentate and monodentate nitrates and possesses an S= 0 ground state, respectively.
