Materials Data on K3Fe(CO2)6 by Materials Project
K3Fe(CO2)6 crystallizes in the cubic P4_132 space group. The structure is three-dimensional. there are three inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are three shorter (2.76 Å) and three longer (3.05 Å) K–O bond lengths. In the second K1+ site, K1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of K–O bond distances ranging from 2.79–3.25 Å. In the third K1+ site, K1+ is bonded in a distorted pentagonal pyramidal geometry to six equivalent O2- atoms. All K–O bond lengths are 2.59 Å. Fe3+ is bonded in a distorted octahedral geometry to six O2- atoms. There are three shorter (2.04 Å) and three longer (2.07 Å) Fe–O bond lengths. There are two inequivalent C3+ sites. In the first C3+ site, C3+ is bonded in a bent 120 degrees geometry to two O2- atoms. There is one shorter (1.24 Å) and one longer (1.29 Å) C–O bond length. In the second C3+ site, C3+ is bonded in a bent 120 degrees geometry to two O2- atoms. There is one shorter (1.24 Å) and one longer (1.31 Å) C–O bond length. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to two K1+ and one C3+ atom. In the second O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one K1+, one Fe3+, and one C3+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to two K1+ and one C3+ atom. In the fourth O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent K1+, one Fe3+, and one C3+ atom.
