A triacontanuclear [Zn12Dy18] cluster: a ring of [Dy4] cubes†
Abstract
The reaction between Dy(NO3)3·6H2O, Zn(OAc)2·4H2O, salicylaldehyde and 2-amino-isobutyric acid, in MeOH in the presence of NEt3 under solvothermal conditions, led to the isolation of the triacontanuclear mixed-metal cluster [ZnII12DyIII18(OH)30(L)12(sal)6(OAc)6(NO3)3(H2O)6](NO3)3·12MeOH·5H2O (1·12MeOH·5H2O), which displays frequency- and temperature-dependent out-of-phase magnetic susceptibility signals.
