Ti3Ga is Hg_xSn-derived structured and crystallizes in the hexagonal P6/mmm space group. Ti(1) is bonded to six equivalent Ti(1) and two equivalent Ga(1) atoms to form TiTi6Ga2 hexagonal bipyramids that share corners with eight equivalent Ti(1)Ti6Ga2 hexagonal bipyramids, edges with eight equivalent Ga(1)Ti6Ga2 hexagonal bipyramids, and edges with sixteen equivalent Ti(1)Ti6Ga2 hexagonal bipyramids. Ga(1) is bonded to six equivalent Ti(1) and two equivalent Ga(1) atoms to form GaTi6Ga2 hexagonal bipyramids that share corners with eight equivalent Ga(1)Ti6Ga2 hexagonal bipyramids and edges with twenty-four equivalent Ti(1)Ti6Ga2 hexagonal bipyramids.
