Results of an experimental study of the influence exerted by the solvent nature on the reaction rate, achieved degree of acid expenditure, selectivity with respect to salts of iron(II) and (III), and phase state of the reaction mixture in a single-stage reaction of iron with benzoic acid and atmospheric oxygen in the presence of a stimulating iodine additive are presented.

The reaction of iron(III) acetylacetonate with molten benzoic acid yields Fe(C6H5COO)2 (2) besides small amounts of Fe3(C6H5COO)4(acac)2 (1), whereas cobalt (III) acetylacetonate or cobalt(II) carbonate quantitatively yield Co(C6H5COO)2 (3).Complex 1 forms triclinic red crystals with the space group P and the lattice constants a = 1016.0(3) pm, b = 1099.9(2) pm,c = 969.8(2) pm, α = 92.68(2) deg, β = 105.67(2) deg, γ = 117.57(2) deg, Z = 1. 3 is obtained as monoclinic violet needles with the space group C2/c and the lattice constants a = 1739.2(4) pm, b = 1413.8(3) pm, c = 1045.3(3) pm, β = 96.26(2) deg, Z = 8. 3 consists of polymeric chains with a zigzag arrangement of the cobalt atoms (Co-Co = 314.5 pm) and an octahedral coordination for Co 1 and (4 + 2)-coordination for Co 2.The benzoato ligands act differently.One benzoate group functions as bridging ligand between adjacent metal atoms, the other acts as a four-dentate ligand by chelating one cobalt atom and bridging its neighbours.Complex 2 was not obtained in form of single crystals, but its properties as well as its IR and Moessbauer spectra suggest a similar structure as for 3.Complex 1 is also polymeric, the chain of iron atoms is nearly linear.The acetylacetonate ligand acts chelating and bridging as a four-dentate ligand, whereas the benzoate anion is only bridging neighbouring Fe atoms.The Fe atoms exhibit octahedral and trigonal bipyramidal coordination. - Keywords: Tetrabenzoato Diacetylacetonato Triiron(II), Dibenzoato Iron(II), Dibenzoato Cobalt(II), Synthesis, Crystal Structure
