N2 - Fe1.087Te exhibits three phases in the pressure range from ambient to 16.6GPa and becomes amorphous at higher pressures. All three phases have tetragonal symmetry. The low pressure T-phase is stable in the pressure range 0≤P<4.1GPa and is found to be relatively soft having zero pressure bulk modulus B 0=36(1)GPa. The intermediate cT-phase is less compressible with B 0=88(5)GPa and stable in the pressure range 4.1≤P<10GPa while a more compressible phase was observed between 10 and 16.6GPa.
