Title: Materials Data on LaAs2 by Materials Project

Abstract

LaAs2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. La3+ is bonded in a 9-coordinate geometry to nine As+1.50- atoms. There are a spread of La–As bond distances ranging from 3.07–3.29 Å. There are two inequivalent As+1.50- sites. In the first As+1.50- site, As+1.50- is bonded in a 6-coordinate geometry to four equivalent La3+ and two As+1.50- atoms. There are one shorter (2.51 Å) and one longer (2.55 Å) As–As bond lengths. In the second As+1.50- site, As+1.50- is bonded to five equivalent La3+ and one As+1.50- atom to form a mixture of distorted edge and corner-sharing AsLa5As pentagonal pyramids.
