In this work, the fabrication of [Fe(pz)Pt(CN) 4 ] (pz = pyrazine) thin films by means of matrix‐assisted pulsed laser evaporation (MAPLE) was investigated. As starting material, a cryogenically cooled suspension of nanocrystalline [Fe(pz)Pt(CN) 4 ] (0.35wt.‐%) in a mixture of 1,1 ‐dichloroethane and polyethylene glycol (PEG) was used. Films of a thickness up to 150–200 nm were deposited on Si substrates by laser ablation at λ = 1064 nm of the cryogenically cooled material. PEG impregnated films exhibit a cooperative first‐order hysteretic spin crossover behavior around 155 K as detected by Raman spectroscopy. Most interestingly, deposition of a crystalline material was achieved through MAPLE deposition.
