ErMn2Si2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Er3+ is bonded in a distorted body-centered cubic geometry to eight equivalent Si4- atoms. All Er–Si bond lengths are 3.00 Å. Mn+2.50+ is bonded to four equivalent Si4- atoms to form a mixture of corner and edge-sharing MnSi4 tetrahedra. All Mn–Si bond lengths are 2.36 Å. Si4- is bonded in a 9-coordinate geometry to four equivalent Er3+, four equivalent Mn+2.50+, and one Si4- atom. The Si–Si bond length is 2.45 Å.
