Materials Data on GeAs by Materials Project
GeAs is Hittorf-derived structured and crystallizes in the monoclinic C2/m space group. The structure is one-dimensional and consists of two GeAs ribbons oriented in the (0, 1, 0) direction. there are three inequivalent Ge3+ sites. In the first Ge3+ site, Ge3+ is bonded in a trigonal non-coplanar geometry to three As3- atoms. There are one shorter (2.48 Å) and two longer (2.49 Å) Ge–As bond lengths. In the second Ge3+ site, Ge3+ is bonded in a trigonal non-coplanar geometry to three As3- atoms. There are one shorter (2.49 Å) and two longer (2.50 Å) Ge–As bond lengths. In the third Ge3+ site, Ge3+ is bonded in a trigonal non-coplanar geometry to three As3- atoms. There are two shorter (2.50 Å) and one longer (2.52 Å) Ge–As bond lengths. There are three inequivalent As3- sites. In the first As3- site, As3- is bonded in a distorted T-shaped geometry to three Ge3+ atoms. In the second As3- site, As3- is bonded in a distorted T-shaped geometry to three Ge3+ atoms. In the third As3- site, As3- is bonded in a distorted T-shaped geometry to three Ge3+ atoms.
