MoAs2 is Magnesium tetraboride-like structured and crystallizes in the monoclinic C2/m space group. Mo(1) is bonded in a 8-coordinate geometry to three equivalent As(1) and five 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 As(1) atoms. In the second As site, As(2) is bonded in a 8-coordinate geometry to five equivalent Mo(1) and three equivalent As(2) atoms.
MoAs2 is Magnesium tetraboride-like structured and crystallizes in the monoclinic C2/m space group. Mo(1) is bonded in a 8-coordinate geometry to three equivalent As(1) and five equivalent As(2) atoms. There are two shorter (2.58 Å) and one longer (2.59 Å) Mo(1)-As(1) bond length. There are a spread of Mo(1)-As(2) bond distances ranging from 2.61-2.74 Å. 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 As(1) atoms. There is one shorter (2.44 Å) and two longer (2.74 Å) As(1)-As(1) bond lengths. In the second As site, As(2) is bonded in a 8-coordinate geometry to five equivalent Mo(1) and three equivalent As(2) atoms. There is one shorter (2.93 Å) and two longer (2.95 Å) As(2)-As(2) bond lengths.
