Abstract

Anisotropic coordination nanoparticles of the photomagnetic network Cs^I₂Cu^II₇[Mo^IV(CN)₈]₄ are obtained through a surfactant-free high-yield synthetic procedure in water. These particles are organised as Langmuir–Blodgett films with a preferential orientation of the nano-objects within the film that exhibit a magnetic bistability below 20 K with a very large coercivity due to an efficient photo-transformation.
