On The Crystal Structure And Conductivity Of Na3p
ZEITSCHRIFT FUR ANORGANISCHE UND ALLGEMEINE CHEMIE(2021)
摘要
As a potential material for Na-ion battery systems and on the basis of a structural discussion of compounds formerly believed to crystallize in the so-called Na3As type the structure of Na3P has been reinvestigated. Na3P is found to crystallize in the Cu3P type, analogous to Na3As and is described by a three times larger unit cell [P6(3)cm, a = 8.61224(10) angstrom and c = 8.81949(10) angstrom] compared to the former model [P6(3)/mmc, a = 4.9512(5) angstrom and c = 8.7874(13) angstrom]. As a structural manifestation of this symmetry reduction corrugated layers of Na and P atoms are observed which had formerly to be described as planar. The high purity of the material further enables the determination of its properties, showing mainly semiconducting behavior with a conductivity of 12 S center dot cm(-1) at room temperature.
