In In As As
InAs is alpha carbon monoxide-like structured and crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of two indium arsenide molecules. In(1) is bonded in a single-bond geometry to one As(1) atom. The In(1)-As(1) bond length is 0.58 Å. As(1) is bonded in a single-bond geometry to one In(1) atom.
