The material structure described by BaMgSi is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. Ba(1) is bonded in a 9-coordinate geometry to four equivalent Mg(1) and five equivalent Si(1) atoms. Mg(1) is bonded to four equivalent Ba(1) and four equivalent Si(1) atoms to form a mixture of distorted face and edge-sharing MgBa4Si4 tetrahedra. Si(1) is bonded in a 9-coordinate geometry to five equivalent Ba(1) and four equivalent Mg(1) atoms. is represented by the CIF file [CIF]
