YbFe(CN)6(O2)2 is alpha Rhenium trioxide-derived structured and crystallizes in the orthorhombic Cmcm space group. The structure consists of four tetraoxetane molecules inside a YbFe(CN)6 framework. In the YbFe(CN)6 framework, Yb(1) is bonded in a distorted pentagonal pyramidal geometry to two equivalent N(2) and four equivalent N(1) atoms. Fe(1) is bonded in an octahedral geometry to two equivalent C(1) and four equivalent C(2) atoms. There are two inequivalent C sites. In the first C site, C(1) is bonded in a linear geometry to one Fe(1) and one N(2) atom. In the second C site, C(2) is bonded in a linear geometry to one Fe(1) and one N(1) atom. There are two inequivalent N sites. In the first N site, N(1) is bonded in a linear geometry to one Yb(1) and one C(2) atom. In the second N site, N(2) is bonded in a distorted linear geometry to one Yb(1) and one C(1) atom.
