The title compounds, [Fe 4 (C 2 H 3 O 2 ) 6 (C 7 H 4 O 3 )FO(C 5 H 5 N) 3 ]·C 5 H 5 N·0.24H 2 O ( 1-F ) and [Fe 4 (C 2 H 3 O 2 ) 6 (C 7 H 4 O 3 )ClO(C 5 H 5 N) 3 ]·H 2 O ( 1-Cl ) were synthesized using a self-assembly reaction in methanol and pyridine with stoichiometric addition of salicyl-hydroxamic acid (H 3 shi), acetic acid (HOAc), and the appropriate ferric halide salt. The compounds crystallize as solvates, where 1-F has one pyridine mol-ecule that is disordered about a twofold axis and one water mol-ecule with an occupancy of 0.24 (2); and 1-Cl has one water mol-ecule that is disordered over two sites with occupancies of 0.71 (1) and 0.29 (1). The space groups for each analog differ as 1-F crystallizes in Fdd 2 while 1-Cl crystallizes in P 2 1 . The difference in packing is due to changes in the inter-molecular inter-actions involving the different halides. The two mol-ecules are mostly isostructural, differing only by the torsion of the pyrine ligands and slight orientation changes in the acetate ligands. All of the iron(III) ions are in six-coordinate octa-hedral ligand field geometries but each one exhibits a unique coordination environment with various numbers of O (four to six) and N (nought to two) atom donors. Bond-valence sums confirm each iron is trivalent. The hydroximate ligand is bound to three iron(III) ions using a fused chelate motif similar to those in metallacrown compounds.
