dc.description.abstract | 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 penta-rubidium bis[tris(oxalate) ferrate (III)], NaRb5[Fe(C2O4)3]2. One enantiomer of the salt crystallizes in the cubic space group P4332 with Z = 4 and a Flack absolute structure parameter x = -0.01(1) and its chiral counterpart in the space group P4132 with x = -0.00(1). All metal ions are at crystallographic special positions: the Fe(III) ion is on a threefold axis, coordinated by three oxalate dianions in a propeller-like conformation. One of the two independent Rb(I) ions is on a twofold axis in an eightfold coordination with neighboring oxalate oxygen atoms, and the other one on a threefold axis in a sixfold RbO6 coordination. The sodium ion is at a site of D3 point group symmetry in a trigonal-antiprismatic NaO6 coordination. | |
