Cr3C is Cementite structured and crystallizes in the orthorhombic Pnma space group. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded in a 3-coordinate geometry to three equivalent C(1) atoms. In the second Cr site, Cr(2) is bonded in a bent 150 degrees geometry to two equivalent C(1) atoms. C(1) is bonded in a 8-coordinate geometry to two equivalent Cr(2) and six equivalent Cr(1) atoms.
Cr3C is Cementite structured and crystallizes in the orthorhombic Pnma space group. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded in a 3-coordinate geometry to three equivalent C(1) atoms. There are a spread of Cr(1)-C(1) bond distances ranging from 2.04-2.28 Å. In the second Cr site, Cr(2) is bonded in a bent 150 degrees geometry to two equivalent C(1) atoms. There is one shorter (2.02 Å) and one longer (2.07 Å) Cr(2)-C(1) bond length. C(1) is bonded in a 8-coordinate geometry to two equivalent Cr(2) and six equivalent Cr(1) atoms.
