Synthesis and Crystal Structure of Mononuclear Iron(III) Complex of 6-Hydroxy-2-(5-bromo-2-hydroxyphenyl)-5-(5-bromosalicylideneamino)-benzoxazole

Abstract

The mononuclear complex [Fe(HL-Br)Cl(py)2]·C2H5OC2H5, [H3L-Br = 6-hydroxy-2-(5-bromo-2-hydroxyphenyl)-5-(5-bromosalicylideneamino)benzoxazole] was synthesized and characterized by single-crystal X-ray analysis. The compound crystallizes in the triclinic system, spaces group P1 and Z = 2 with cell parameters a = 9.0436(9)A, b = 14.284(4)A, c = 15.320(3)A, α = 64.002(14)°, β = 81.430(11)°, γ = 80.642(15)°, V = 1748.4(6)A3. The ligand (HL-Br)2- acts as a tridentate form, and the iron(III) has octahedral geometry. The crystal packing is stabilized by two types of inter molecular π-π stacking interactions.
