Materials Data on ReGeAs by Materials Project
ReGeAs is Magnesium tetraboride-derived structured and crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. Re is bonded in a 8-coordinate geometry to five equivalent Ge and three equivalent As atoms. There are a spread of Re–Ge bond distances ranging from 2.67–2.76 Å. There are two shorter (2.51 Å) and one longer (2.57 Å) Re–As bond lengths. Ge is bonded in a 7-coordinate geometry to five equivalent Re and two equivalent Ge atoms. Both Ge–Ge bond lengths are 2.83 Å. As is bonded in a 4-coordinate geometry to three equivalent Re and one As atom. The As–As bond length is 2.40 Å.
