Abstract:
The reaction of MnCl2路4H2O with t-BuPO 3H2 in the presence of triethylamine afforded the tridecanuclear cage, [MnIIMnIII12(渭 4-O)6(渭-翱贬)6(O3P-t-Bu) 10(OH2)2(DMF)4] 路[2MeOH路4DMF] (1). The structural analysis of 1 reveals that it is a mixed-valent complex containing a [MnIIMnIII12(渭4-O)6] core. The centre of the core is occupied by a MnII ion which is surrounded by 12 MnIII ions. The latter are connected to each other by six 渭-OH- and 10 t-BuPO32- ligands. The vacant coordination sites of six MnIII ions situated in the periphery are occupied by four DMF and two water molecules. Magnetic studies on 1 reveal a frequency-dependent response which is characteristic of single-molecule magnets. 漏 2014 Elsevier Ltd.
