Cr(CN)3 is alpha Rhenium trioxide-derived structured and 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 pentagonal pyramidal geometry to two equivalent N(2) and four equivalent N(1) atoms. In the second Cr site, Cr(2) is bonded in an octahedral geometry to two equivalent C(2) and four equivalent C(1) atoms. There are two inequivalent C sites. In the first C site, C(1) is bonded in a linear geometry to one Cr(2) and one N(1) atom. In the second C site, C(2) is bonded in a linear geometry to one Cr(2) and one N(2) atom. There are two inequivalent N sites. In the first N site, N(1) is bonded in a linear geometry to one Cr(1) and one C(1) atom. In the second N site, N(2) is bonded in a linear geometry to one Cr(1) and one C(2) atom.
