Four complexes were synthesized using bis(pentamethylcyclopentadienyl)iron Fe(C5Me5)2 as an organometallic donor and three anilic acids (2,5-dibromo-3,6-dihydroxy-1,4-benzoquinone; BA, 2,5-dichloro-3,6-dihydroxy-1,4-benzoquinone; CA and 2,5-dicyano-3,6-dihydroxy-1,4-benzoquinone; CNA) as an organic acceptor. The molecular-based structures with different stoichiometric ratios [1:1, 1:1:1(H2O) and 2:1] of these complexes have been determined by X-ray crystallographic analysis and elemental analysis. These complexes have a one-dimensional alternated stacking arrangement as ···D+A-D+A- ··· type. Close contacts between the bromine atoms and oxygen atoms of the BA units are observed in the structure [Fe(C5Me5)2](BA) (1) of 1:1 composition. Interestingly, the structures [Fe(C5Me5)2](CA)(H2O) (2) and [Fe(C5Me5)2](CNA)(H2O) (3) of 1:1:1(H2O) ratio contain one-dimensional molecular tape structures with the combination of the CA or the CNA units and water molecules via O-H···O hydrogen bonds. Different stoichiometric ratios and structures are found from the CNA complexes [Fe(C5Me5)2](CNA)(H2O) (3) and [Fe(C5Me5)2]2(CNA) (4).
