Mn3RhCo2As3 crystallizes in the orthorhombic Amm2 space group. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a 11-coordinate geometry to two equivalent Rh(1), four equivalent Co(1), one As(1), and four equivalent As(2) atoms. In the second Mn site, Mn(2) is bonded in a 11-coordinate geometry to two equivalent Rh(1), four equivalent Co(1), one As(1), and four equivalent As(2) atoms. Rh(1) is bonded to two equivalent Mn(1), four equivalent Mn(2), two equivalent Co(1), two equivalent As(1), and two equivalent As(2) atoms to form distorted face-sharing RhMn6Co2As4 cuboctahedra. Co(1) is bonded in a 4-coordinate geometry to two equivalent Mn(1), four equivalent Mn(2), one Rh(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 one Mn(1), two equivalent Mn(2), two equivalent Rh(1), and four equivalent Co(1) atoms. In the second As site, As(2) is bonded in a 9-coordinate geometry to two equivalent Mn(1), four equivalent Mn(2), one Rh(1), and two equivalent Co(1) atoms.
