TiSiY is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. Y(1) is bonded in a 5-coordinate geometry to five equivalent Si(1) atoms. Ti(1) is bonded to four equivalent Si(1) atoms to form a mixture of distorted edge and corner-sharing TiSi4 cuboctahedra. Si(1) is bonded in a 9-coordinate geometry to five equivalent Y(1) and four equivalent Ti(1) atoms.
TiSiY is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. Y(1) is bonded in a 5-coordinate geometry to five equivalent Si(1) atoms. There are four shorter (2.98 Å) and one longer (3.20 Å) Y(1)-Si(1) bond length. Ti(1) is bonded to four equivalent Si(1) atoms to form a mixture of distorted edge and corner-sharing TiSi4 cuboctahedra. All Ti(1)-Si(1) bond lengths are 2.70 Å. Si(1) is bonded in a 9-coordinate geometry to five equivalent Y(1) and four equivalent Ti(1) atoms.
