    • The present invention is directed to a family of trimetallic nitride endohedral metalloheterofullerenes having the formula Ax X3-x N@Cn N, (x=0, 1, 2 or 3) (n=number of carbon atoms in the cage, typically between 59 and 199), wherein A and X are metal atoms encased within the cage, C is carbon and N is nitrogen. A and X are preferably selected from rare earth elements or group IIIB elements. A or X metal atoms are scandium, yttrium, lanthanum, gadolinium, lutetium, holmium, erbium, thulium, dysprosium, neodymium, cerium, praseodymium and ytterbium. Representative embodiments include Sc3N@C79N, Y3N@C79N, La3N@C79N, Tb3N@C79N, Ho3N@C79N, LaSc2N@C79N, PrSc2N@C79N, GdSc2N@C79N, La2ScN@C79N, and Gd2ScN@C79N. The present invention is also directed to a method of making the inventive endohedral metalloheterofullerenes having the formula AxX3-xN@CnN. These methods involve use of oxidizing gases (e.g. O2 and NOx) coupled with combustion as a means for making trimetallic nitride clusters encapsulated in heteroatom CnN cages made of both carbon and nitrogen.
    • 本发明涉及一种具有式ⅩⅩX3-x N @ Cn N(x = 0,1,2或3)的三金属氮化物内嵌型金属杂多富勒烯(n =笼中的碳原子数,通常为59 和199),其中A和X是包封在笼中的金属原子,C是碳,N是氮。 A和X优选选自稀土元素或IIIB族元素。 A或X金属原子是钪,钇,镧,钆,镥,钬,铒,ium,镝,钕,铈,镨和镱。 代表性的实施方案包括Sc3N @ C79N,Y3N @ C79N,La3N @ C79N,Tb3N @ C79N,Ho3N @ C79N,LaSc2N @ C79N,PrSc2N @ C79N,GdSc2N @ C79N,La2ScN @ C79N和Gd2ScN @ C79N。 本发明还涉及制备具有式AxX3-xN @ CnN的本发明的内嵌金属热富勒烯的方法。 这些方法包括使用与燃烧耦合的氧化气体(例如O 2和NO x)作为用于制造包封在由碳和氮两者制成的杂原子CnN笼中的三金属氮化物团簇的手段。
