Gadolinium diiodide is an

saturation magnetization of 7.3  B; it exhibits a large negative magnetoresistance (~70%) at 7 T near room temperature.[3] It can be obtained by reacting gadolinium and gadolinium(III) iodide at a high temperature:[4]

Gd + 2 GdI3 → 3 GdI2

It can react with hydrogen at high temperature (800 °C) to obtain gadolinium hydrogen iodide (GdI2H0.97[5]).[6]
