The material structure described by Cr(CN)6Cr(NH3)6 is Tungsten structured and crystallizes in the trigonal R-3 space group. The structure is zero-dimensional and consists of three chromium hexacyanide molecules and three Cr(NH3)6 clusters. In each Cr(NH3)6 cluster, Cr(2) is bonded in an octahedral geometry to six equivalent N(2) atoms. N(2) is bonded in a distorted trigonal non-coplanar geometry to one Cr(2), one H(1), one H(2), and one H(3) atom. There are three inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one N(2) atom. In the second H site, H(2) is bonded in a single-bond geometry to one N(2) atom. In the third H site, H(3) is bonded in a single-bond geometry to one N(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
