![]() ![]() To design molecular spin qubits with enhanced quantum coherence, a control of the coupling between the local vibrations and the spin states is crucial, which could be realized in principle by engineering molecular structures via coordination chemistry. ![]() ![]() Remarkably, C 2 v (19138)‐C 76 represents as the first Eu‐containing EMF with a cage that violates the isolated‐pentagon‐rule and C 2 v (3)‐C 78 is the first C 78 ‐based EMF stabilized by merely one metal atom. Consistently, all the isolated Eu‐EMFs are actually mono‐EMFs including D 3 h (1)‐C 74, C 2 v (19138)‐C 76, C 2 v (3)‐C 78, C 2 v (3)‐C 80 and D 3 d (19)‐C 84 which are identified by crystallography in this work. Theoretical calculations demonstrate that the encapsulation energy of the endohedral metal element accounts for the selective formation of the mono‐EMFs and rationalize similar observations for EMFs containing other metals like Ca, Sr, Ba or Yb. Mass spectroscopy reveals that mono‐EMFs (EuC 2n ) prevail in the Eu‐containing soot. Although the coexistence of diverse EMF‐species in the soot is common for rare earth metals, we herein report for the first time that europium tends to induce the preferential formation of mono‐EMFs instead. This study paves the way for low-cost and high-yield syntheses of pricey endohedral fullerenes.Įntrapping one to three metal atom(s) or a metallic cluster inside fullerene cages affords endohedral metallofullerenes (EMFs) classified as mono‐EMFs, di‐EMFs, tri‐EMFs and cluster‐EMFs, respectively. Moreover, the molecular structures of three isomers of are unambiguously determined by single-crystal X-ray diffraction, indicating that the encapsulated triangular D圜N cluster is tunable due to the strong metal-cage interactions. Under the optimized Dy::C molar ratio of 1:1:15, the sum yield of isolated (2n=76, 82) CYCFs produced by using Fe43 is about 2.8 times higher than that obtained by using gaseous N2 source. Herein, we employ an ancient pigment, prussian blue (Fe43), as a cheap solid cyanide/nitrogen dual-source, affording simplified yet high-yield simultaneous syntheses of novel dysprosium (Dy)-based metal cyanide clusterfullerenes (CYCFs) and metal nitride clusterfullerenes Surprisingly, the (CN)- anion of Fe43 survives under the extremely high temperature (up to 4000 K) of plasma generated via DC-arc discharge, and functions as the cyanide source of CYCFs. He is Chairperson, Member of the Disclosure Committee and Member of the Risk Committee.Endohedral clusterfullerenes featuring encapsulation of metal clusters within carbon cages exhibit intriguing physical and chemical properties inaccessible by empty fullerenes, and so far their syntheses are predominantly fulfilled by using gaseous sources, suffering from low yield and requiring an additional gas inlet and a heating pretreatment up to 1000 ☌.
