Bar-headed goose fluoromethaemoglobin (fluoromet-Hb) complexed with inositol hexaphosphate (IHP) has been crystallized using PEG 6000 as precipitant. The crystal belongs to space group P21, with unit-cell parameters a = 59.8, b = 72.0, c = 79.8 Å, β = 102.1°, and diffracts to 2.5 Å resolution. To prove the presence of IHP, the structure was determined by the molecular-replacement method. IHP was observed at the entrance to the central cavity between the N and C termini of two β subunits.
