The structure described by BaTi2As2O crystallizes in the tetragonal P4/mmm space group. Ba(1) is bonded in a body-centered cubic geometry to eight equivalent As(1) atoms. Ti(1) is bonded in a distorted linear geometry to four equivalent As(1) and two equivalent O(1) atoms. As(1) is bonded in a 8-coordinate geometry to four equivalent Ba(1) and four equivalent Ti(1) atoms. O(1) is bonded in a square co-planar geometry to four equivalent Ti(1) atoms. is represented by the CIF file [CIF]
