NaAlSi is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. Na(1) is bonded in a 5-coordinate geometry to five equivalent Si(1) atoms. Al(1) is bonded to four equivalent Si(1) atoms to form a mixture of distorted corner and edge-sharing AlSi4 tetrahedra. Si(1) is bonded in a 9-coordinate geometry to five equivalent Na(1) and four equivalent Al(1) atoms.
NaAlSi is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. Na(1) is bonded in a 5-coordinate geometry to five equivalent Si(1) atoms. There are four shorter (3.11 Å) and one longer (3.13 Å) Na(1)-Si(1) bond length. Al(1) is bonded to four equivalent Si(1) atoms to form a mixture of distorted corner and edge-sharing AlSi4 tetrahedra. All Al(1)-Si(1) bond lengths are 2.55 Å. Si(1) is bonded in a 9-coordinate geometry to five equivalent Na(1) and four equivalent Al(1) atoms.
