Materials Data on AgP2 by Materials Project

Abstract

AgP2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Ag2+ is bonded in a 4-coordinate geometry to four P1- atoms. There are a spread of Ag–P bond distances ranging from 2.52–2.69 Å. There are two inequivalent P1- sites. In the first P1- site, P1- is bonded to three equivalent Ag2+ and two equivalent P1- atoms to form distorted PAg3P2 trigonal bipyramids that share corners with five equivalent PAgP3 tetrahedra, corners with six equivalent PAg3P2 trigonal bipyramids, and an edgeedge with one PAg3P2 trigonal bipyramid. There are one shorter (2.21 Å) and one longer (2.22 Å) P–P bond lengths. In the second P1- site, P1- is bonded to one Ag2+ and three P1- atoms to form PAgP3 tetrahedra that share corners with two equivalent PAgP3 tetrahedra and corners with five equivalent PAg3P2 trigonal bipyramids. The P–P bond length is 2.26 Å.
