    • The present invention relates to a single source metalloorganic precursor compound of the formula: (2-NR-Q-).sub.l M-A.sub.m (I=0-4, m=0-4, l+m=2 or 4) wherein M is selected form the Group 14 elements of Germanium, Tin or Lead;A and R are independently selected from: amide, alkyl having from 1 to 20 carbon atoms, aryl, substituted aryl, or -Q'-2-NR'L.sub.n (n=1-4) wherein L is selected from nothing or a Lewis base ligand; Q and Q' are each independently selected from Group VIa elements of sulfur, selenium, or tellurium; and 2-NR and 2-NR' are each independently selected from N-heterocyclic aryl or its derivatives. Methods of producing these compounds are also disclosed. These precursor materials provide in a single compound the binary, tertiary, or quaternary metals in a ratio to each other that is controllable by a judicious choice of metal atoms and organic substituents. The metal alloys are useful in a variety for electronic applications, particularly in semiconductors and solar energy.
    • 本发明涉及式(2-NR-Q-)1 M-Am(I = 0-4,m = 0-4,1 + m = 2或4)的单源金属有机前体化合物,其中M为 选自锗,锡或铅的第14组元素; A和R独立地选自:酰胺,具有1至20个碳原子的烷基,芳基,取代的芳基或-Q'-2-NR'Ln(n = 1-4)其中L选自无或路易斯 碱配体; Q和Q'各自独立地选自Ⅵa族元素的硫,硒或碲; 和2-NR和2-NR'各自独立地选自N-杂环芳基或其衍生物。 还公开了制备这些化合物的方法。 这些前体材料在单一化合物中提供彼此成比例的二价,三级或四级金属,其可通过明智地选择金属原子和有机取代基来控制。 金属合金可用于各种电子应用,特别是半导体和太阳能。
