A Study of the Structure and Electronic and Thermal Properties of Quasi-One-Dimensional La3MoO7

Abstract

The structure of La3MoO7was solved inP212121withZ=4 anda=7.597(1) Å,b=7.7192(4) Å andc=11.0953(8) Å and refined to the reliability factors ofR(F)=0.0366 andwR(F2)=0.0782 for 102 variables and 5352 reflections. A structural feature of interest is the presence of zigzag chains oftrans-corner-sharing octahedra of composition MoO5−5parallel to theb-axis. Resistivity data taken along theb-axis direction show semiconducting behavior in the range 140 …
