The material described by TiMnAs crystallizes in the hexagonal P-62m space group. Ti(1) is bonded to two equivalent As(1) and two equivalent As(2) atoms to form a mixture of distorted corner and edge-sharing TiAs4 tetrahedra. Mn(1) is bonded in a 5-coordinate geometry to one As(2) and four equivalent As(1) atoms. There are two inequivalent As sites. In the first As site, As(2) is bonded in a 9-coordinate geometry to six equivalent Ti(1) and three equivalent Mn(1) atoms. In the second As site, As(1) is bonded in a 9-coordinate geometry to three equivalent Ti(1) and six equivalent Mn(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
