MnRhAs crystallizes in the hexagonal P-62m space group. Mn(1) is bonded in a 11-coordinate geometry to six equivalent Rh(1), one As(1), and four equivalent As(2) atoms. Rh(1) is bonded in a 10-coordinate geometry to six equivalent Mn(1), two equivalent As(1), and two equivalent As(2) atoms. There are two inequivalent As sites. In the first As site, As(1) is bonded in a 9-coordinate geometry to three equivalent Mn(1) and six equivalent Rh(1) atoms. In the second As site, As(2) is bonded in a 9-coordinate geometry to six equivalent Mn(1) and three equivalent Rh(1) atoms.
MnRhAs crystallizes in the hexagonal P-62m space group. Mn(1) is bonded in a 11-coordinate geometry to six equivalent Rh(1), one As(1), and four equivalent As(2) atoms. There are two shorter (2.84 Å) and four longer (2.99 Å) Mn(1)-Rh(1) bond lengths. The Mn(1)-As(1) bond length is 2.68 Å. All Mn(1)-As(2) bond lengths are 2.70 Å. Rh(1) is bonded in a 10-coordinate geometry to six equivalent Mn(1), two equivalent As(1), and two equivalent As(2) atoms. Both Rh(1)-As(1) bond lengths are 2.49 Å. Both Rh(1)-As(2) bond lengths are 2.45 Å. There are two inequivalent As sites. In the first As site, As(1) is bonded in a 9-coordinate geometry to three equivalent Mn(1) and six equivalent Rh(1) atoms. In the second As site, As(2) is bonded in a 9-coordinate geometry to six equivalent Mn(1) and three equivalent Rh(1) atoms.
