- W1639608399 abstract "We have studied the local site assignment as well as the structural and dynamic properties of the alkali ions in superconducting ${mathrm{K}}_{2}$${mathrm{RbC}}_{60}$, ${mathrm{K}}_{2}$${mathrm{CsC}}_{60}$, ${mathrm{Rb}}_{2}$${mathrm{CsC}}_{60}$, and ${mathrm{Rb}}_{3}$${mathrm{C}}_{60}$ compounds by x-ray absorption fine structure (EXAFS) measurements at the alkali ions K, Rb, and Cs in the temperature range 14--300 K. In the ternary ${mathit{A}}_{2}$B${mathrm{C}}_{60}$ systems a strong preferential site occupation is observed, where the smaller alkali ions (A) are placed in tetrahedral sites and the larger ones (B) in octahedral sites. This site ordering allows a separate structural analysis of tetrahedral and octahedral sites. A quantitative analysis of the tetrahedral site (A) dopants yields the neighbor distances R(A-C), coordination numbers ${mathit{N}}_{mathit{C}}$ and second cumulants ${mathrm{ensuremath{sigma}}}^{2}$. A similar analysis of the tetrahedral sites in ${mathrm{Rb}}_{3}$${mathrm{C}}_{60}$ was performed by creating difference spectra with the ${mathrm{K}}_{2}$${mathrm{RbC}}_{60}$ system. A multishell analysis of the octahedral sites (B) yields an off-center position of the B dopants. The off-center displacement scales with the size of the octahedral site and inversely with the ionic radius of the B dopant. A preferential displacement in the (1,1,1) direction is discussed in conjunction with possible carbon neighbor configurations at the octahedral sites. textcopyright{} 1996 The American Physical Society." @default.
