Materials Data on GdCoSi by Materials Project
GdCoSi is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Gd3+ is bonded in a 5-coordinate geometry to five equivalent Si4- atoms. There are four shorter (2.95 Å) and one longer (3.40 Å) Gd–Si bond lengths. Co1+ is bonded to four equivalent Si4- atoms to form a mixture of edge and corner-sharing CoSi4 tetrahedra. All Co–Si bond lengths are 2.34 Å. Si4- is bonded in a 9-coordinate geometry to five equivalent Gd3+ and four equivalent Co1+ atoms.
