Cr Cr In As
Cr2InAs crystallizes in the trigonal R3m space group. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded in a single-bond geometry to four equivalent Cr(2), three equivalent In(1), and one As(1) atom. There are three shorter (2.73 Å) and one longer (3.34 Å) Cr(1)-Cr(2) bond length. All Cr(1)-In(1) bond lengths are 2.70 Å. The Cr(1)-As(1) bond length is 0.69 Å. In the second Cr site, Cr(2) is bonded in a distorted hexagonal planar geometry to four equivalent Cr(1), three equivalent In(1), and three equivalent As(1) atoms. All Cr(2)-In(1) bond lengths are 2.70 Å. All Cr(2)-As(1) bond lengths are 2.70 Å. In(1) is bonded in a 10-coordinate geometry to three equivalent Cr(1), three equivalent Cr(2), and four equivalent As(1) atoms. There are three shorter (2.73 Å) and one longer (3.34 Å) In(1)-As(1) bond length. As(1) is bonded in a single-bond geometry to one Cr(1), three equivalent Cr(2), and four equivalent In(1) atoms.
