Cu(FeCu(CN)6)2 is alpha Rhenium trioxide-derived structured and crystallizes in the tetragonal P-4m2 space group. The structure consists of one 7440-50-8 atom inside a FeCu(CN)6 framework. In the FeCu(CN)6 framework, Fe(1) is bonded in an octahedral geometry to one N(2), one N(3), and four equivalent N(1) atoms. Cu(1) is bonded in an octahedral geometry to one C(2), one C(3), and four equivalent C(1) atoms. There are three inequivalent C sites. In the first C site, C(1) is bonded in a linear geometry to one Cu(1) and one N(1) atom. In the second C site, C(2) is bonded in a linear geometry to one Cu(1) and one N(2) atom. In the third C site, C(3) is bonded in a linear geometry to one Cu(1) and one N(3) atom. There are three inequivalent N sites. In the first N site, N(1) is bonded in a linear geometry to one Fe(1) and one C(1) atom. In the second N site, N(2) is bonded in a linear geometry to one Fe(1) and one C(2) atom. In the third N site, N(3) is bonded in a linear geometry to one Fe(1) and one C(3) atom.
