Synthesis and characterization of K(In6.5Ag6.5)

摘要

The pseudo-ternary compound K(In6.5Ag6.5) has been synthesized from the elements and either excess indium or excess indium and silver. Single-crystal X-ray diffraction shows that K(In6.5Ag6.5) crystallizes in the cubic space group Fm (3) over barc, a = 13.5101(6) angstrom (Z = 8), and adopts the NaZn13 structure type (R-1 = 0.0338). Four probe resistivity measurements show K(In6.5Ag6.5) to be a metal with a room temperature resistivity of 81 mu Omega cm and a weak temperature dependence. (c) 2005 Elsevier Inc.
