MoMnAs2 crystallizes in the orthorhombic Pmn2_1 space group. Mo(1) is bonded in a 10-coordinate geometry to four equivalent Mn(1), three equivalent As(1), and three equivalent As(2) atoms. Mn(1) is bonded in a 6-coordinate geometry to four equivalent Mo(1), three equivalent As(1), and three equivalent As(2) atoms. There are two inequivalent As sites. In the first As site, As(1) is bonded in a 6-coordinate geometry to three equivalent Mo(1) and three equivalent Mn(1) atoms. In the second As site, As(2) is bonded in a 3-coordinate geometry to three equivalent Mo(1) and three equivalent Mn(1) atoms.
MoMnAs2 crystallizes in the orthorhombic Pmn2_1 space group. Mo(1) is bonded in a 10-coordinate geometry to four equivalent Mn(1), three equivalent As(1), and three equivalent As(2) atoms. There are a spread of Mo(1)-Mn(1) bond distances ranging from 2.99-3.06 Å. There is one shorter (2.48 Å) and two longer (2.57 Å) Mo(1)-As(1) bond lengths. There are two shorter (2.58 Å) and one longer (2.67 Å) Mo(1)-As(2) bond length. Mn(1) is bonded in a 6-coordinate geometry to four equivalent Mo(1), three equivalent As(1), and three equivalent As(2) atoms. There are two shorter (2.54 Å) and one longer (2.74 Å) Mn(1)-As(1) bond length. There is one shorter (2.49 Å) and two longer (2.54 Å) Mn(1)-As(2) bond lengths. There are two inequivalent As sites. In the first As site, As(1) is bonded in a 6-coordinate geometry to three equivalent Mo(1) and three equivalent Mn(1) atoms. In the second As site, As(2) is bonded in a 3-coordinate geometry to three equivalent Mo(1) and three equivalent Mn(1) atoms.
