Materials Data on NdSiGe by Materials Project
NdGeSi crystallizes in the orthorhombic Imma space group. The structure is two-dimensional and consists of two NdGeSi sheets oriented in the (0, 0, 1) direction. Nd2+ is bonded in a 6-coordinate geometry to six equivalent Si4- atoms. There are two shorter (3.18 Å) and four longer (3.20 Å) Nd–Si bond lengths. Ge2+ is bonded in a single-bond geometry to one Si4- atom. The Ge–Si bond length is 2.52 Å. Si4- is bonded in a 9-coordinate geometry to six equivalent Nd2+, one Ge2+, and two equivalent Si4- atoms. Both Si–Si bond lengths are 2.36 Å.
