BaRuFeAs2 crystallizes in the tetragonal I-4m2 space group. Ba(1) is bonded in a distorted body-centered cubic geometry to four equivalent Ru(1) and eight equivalent As(1) atoms. Ru(1) is bonded in a 12-coordinate geometry to four equivalent Ba(1), four equivalent Fe(1), and four equivalent As(1) atoms. Fe(1) is bonded to four equivalent Ru(1) and four equivalent As(1) atoms to form a mixture of distorted face and corner-sharing FeAs4Ru4 tetrahedra. As(1) is bonded in a 8-coordinate geometry to four equivalent Ba(1), two equivalent Ru(1), and two equivalent Fe(1) atoms.
