Synthesis and Characterizations of Heterometallic lanthanide- Zinc Complexes [La2Zn2 (O2CEt)8(C9H7N)2(NO3)2(H2O)2]and [Yb2Zn2(O2CEt)8(C9H7N)2(NO3)2]

Epitaxial adlayers of fullerenes (C60 and C60/C70) on Au(l11) surfaces were prepared by the simple transfer of Langmuir films at air-water interface. The structure of the adlayers are essentially same as those prepared by sublimation. The adlayers are stable and reveal no reaction in the whole double layer potential region in 0.1 M perchloric acid.
