## Abstract By changing the surfactant/water ratio, nanoparticles of the iron(II) spin crossover material, [Fe(NH~2~‐trz)~3~]Br~2~⋅3 H~2~O (with NH~2~‐trz=4‐amino‐1,2,4‐triazole), have been synthesised from 1 μm down to 30 nm (see figure). Magnetic and reflectivity experiments indicate that the cri
