MnRuAs crystallizes in the hexagonal P-62m space group. Mn(1) is bonded in a 4-coordinate geometry to six equivalent Ru(1), two equivalent As(1), and two equivalent As(2) atoms. Ru(1) is bonded in a 11-coordinate geometry to six equivalent Mn(1), one As(2), and four equivalent As(1) atoms. There are two inequivalent As sites. In the first As site, As(1) is bonded in a distorted trigonal planar geometry to three equivalent Mn(1) and six equivalent Ru(1) atoms. In the second As site, As(2) is bonded in a 9-coordinate geometry to six equivalent Mn(1) and three equivalent Ru(1) atoms.
