Materials Data on ZnP2 by Materials Project

Abstract

ZnP2 crystallizes in the tetragonal P4_12_12 space group. The structure is three-dimensional. Zn2+ is bonded to four P1- atoms to form ZnP4 tetrahedra that share corners with four equivalent ZnP4 tetrahedra and corners with eight PZn2P2 tetrahedra. There are a spread of Zn–P bond distances ranging from 2.38–2.42 Å. There are two inequivalent P1- sites. In the first P1- site, P1- is bonded to two equivalent Zn2+ and two equivalent P1- atoms to form distorted PZn2P2 tetrahedra that share corners with four equivalent ZnP4 tetrahedra and corners with eight PZn2P2 tetrahedra. There are one shorter (2.18 Å) and one longer (2.23 Å) P–P bond lengths. In the second P1- site, P1- is bonded to two equivalent Zn2+ and two equivalent P1- atoms to form PZn2P2 tetrahedra that share corners with four equivalent ZnP4 tetrahedra and corners with eight PZn2P2 tetrahedra.
