The structure described by GeCCr3 crystallizes in the orthorhombic Cmcm space group. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded in a distorted L-shaped geometry to three equivalent Ge(1) and two equivalent C(1) atoms. In the second Cr site, Cr(2) is bonded in a distorted bent 150 degrees geometry to two equivalent Ge(1) and two equivalent C(1) atoms. Ge(1) is bonded in a 8-coordinate geometry to two equivalent Cr(2) and six equivalent Cr(1) atoms. C(1) is bonded to two equivalent Cr(2) and four equivalent Cr(1) atoms to form a mixture of corner and edge-sharing CCr6 octahedra. The corner-sharing octahedral tilt angles are 19°. is represented by the CIF file [CIF]
