Ba(GaAl)2 crystallizes in the tetragonal I4/mmm space group. Ba(1) is bonded in a 16-coordinate geometry to eight equivalent Ga(1) and eight equivalent Al(1) atoms. Ga(1) is bonded in a 9-coordinate geometry to four equivalent Ba(1), one Ga(1), and four equivalent Al(1) atoms. Al(1) is bonded to four equivalent Ba(1) and four equivalent Ga(1) atoms to form a mixture of distorted edge, face, and corner-sharing AlBa4Ga4 tetrahedra.
