VFe(CuO2)2 crystallizes in the trigonal R-3m space group. The structure is three-dimensional. V3+ is bonded to six O2- atoms to form edge-sharing VO6 octahedra. All V–O bond lengths are 2.05 Å. Fe3+ is bonded to six O2- atoms to form edge-sharing FeO6 octahedra. All Fe–O bond lengths are 2.05 Å. Cu1+ is bonded in a linear geometry to two O2- atoms. Both Cu–O bond lengths are 1.85 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded to three equivalent Fe3+ and one Cu1+ atom to form a mixture of distorted edge and corner-sharing OFe3Cu trigonal pyramids. The O–Cu bond length is 1.85 Å. In the second O2- site, O2- is bonded to three equivalent V3+ and one Cu1+ atom to form distorted OV3Cu trigonal pyramids that share corners with ten OFe3Cu trigonal pyramids and edges with three equivalent OV3Cu trigonal pyramids. The O–Cu bond length is 1.85 Å. In the third O2- site, O2- is bonded to three equivalent Fe3+ and one Cu1+ atom to form a mixture of distorted edge and corner-sharing OFe3Cu trigonal pyramids. In the fourth O2- site, O2- is bonded to three equivalent V3+ and one Cu1+ atom to form distorted OV3Cu trigonal pyramids that share corners with ten OFe3Cu trigonal pyramids and edges with three equivalent OV3Cu trigonal pyramids. In the fifth O2- site, O2- is bonded to three equivalent Fe3+ and one Cu1+ atom to form a mixture of distorted edge and corner-sharing OFe3Cu trigonal pyramids. All O–Fe bond lengths are 2.05 Å. The O–Cu bond length is 1.85 Å.
