Ultrasound‐Assisted Formation of {Fe₆Ln/Y₄} Wheel‐Shaped Clusters and Condensed {Fe₄Ln/Y₂} Aggregates

Two families of charge‐neutral heterometallic Fe‐4f coordination compounds comprising isobutyrate and amino alcoholate linkers were found to form exclusively upon ultrasonication irradiation. Under one‐pot conditions, the trinuclear precursor [Fe 3 O(O 2 CCHMe 2 ) 6 (H 2 O) 3 ](NO 3 ) · 2(MeCN) · 2(H 2 O) reacts with Ln(NO 3 ) 3 · x H 2 O or Y(NO 3 ) 3 · 6H 2 O, N‐butyldiethanolamine (bdeaH 2 ) and NaN 3 in methanol to yield the decanuclear...
