Spontaneous enanti-omorphism in poly-phased alkaline salts of tris-(oxalato)ferrate(III) : Crystal structure of cubic NaRb5[Fe(C2O4)3]2

We show here that the phenomenon of spontaneous resolution of enantiomers occurs during the crystallization of the sodium and rubidium double salts of the transition metal complex tris(oxalato)ferrate(III), namely sodium pentarubidium bis[tris(oxalato)ferrate(III)], NaRb5...

description	We show here that the phenomenon of spontaneous resolution of enantiomers occurs during the crystallization of the sodium and rubidium double salts of the transition metal complex tris(oxalato)ferrate(III), namely sodium pentarubidium bis[tris(oxalato)ferrate(III)], NaRb<sub>5</sub>[Fe(C<sub>2</sub>O<sub>4</sub>)<sub>3</sub>]<sub>2</sub>. One enantiomer of the salt crystallizes in the cubic space group P4<sub>3</sub>32 with Z = 4 and a Flack absolute structure parameter x = −0.01 (1) and its chiral counterpart in the space group P4<sub>1</sub>32 with x = −0.00 (1). All metal ions are at crystallographic special positions: the iron(III) ion is on a threefold axis, coordinated by three oxalate dianions in a propeller-like conformation. One of the two independent rubidium ions is on a twofold axis in an eightfold coordination with neighbouring oxalate oxygen atoms, and the other one on a threefold axis in a sixfold RbO<sub>6</sub> coordination. The sodium ion is at a site of D<sub>3</sub> point group symmetry in a trigonal–antiprismatic NaO<sub>6</sub> coordination.
