In the presence of dicyanamide and N-butyldiethanolamine (bdeaH 2 ), Fe(III) and Dy(III) precursors self-assemble into the charge-neutral coordination cluster [Fe 6 Dy 3 (ib) 9 (bdea) 6 (MeO) 6 ]·MeOH (1) (ib: isobutyrate) featuring an approximately C 3 -symmetric wheel of edge-sharing FeO 6 and DyO 6 N 2 polyhedra. This is followed by a remarkable self-induced conversion of this cluster into the highly condensed globe-shaped coordination cluster [Fe 7 Dy 4 O 4 (OH) 3 (ib) 9.25 (bdea) 6 (NO 3 ) 0.75 (H 2 O)] (2) in methanolic solution under ambient conditions. The transition from {Fe 6 Dy 3 } to {Fe 7 Dy 4 } coincides with a slowdown of the clusters' magnetization dynamics, as evident from a shift of the onset of significant out-of-phase components of their magnetic ac susceptibility from 3.6 K up to 12 K (1000 Hz) in the absence of a static bias field. |
