This article describes novel optical functionalities such as photomagnetic effects and magnetization-induced second harmonic generation (MSHG) in several cyano-bridged metal assemblies. Single crystal- and film-types of a cyano-bridged Cu - Mo bimetallic assembly, (Cs2Cu7II)-Cu-I [Mo-IV (CN)(8)](4)center dot 6H(2)O, were electrochemically prepared. When this compound was irradiated with light, spontaneous magnetization with a Curie temperature (T-C) of 23 K was observed. Electrochemically prepared Fe-II[Cr-III(CN)(6)](2/3) center dot 5H(2)O thin film, which was a ferromagnet with T-C = 21 K, showed photoreduced magnetization. This photomagnetism is due to the change of ferromagnetic coupling between Fe-II and Cr-III. MSHG was observed in (CsCoII)-Co-I[Cr-III(CN)(6)] center dot 0.5H(2)O. This F (4) over bar 3m-type Prussian blue analog-based magnet is proven to be a piezoelectric ferromagnet, i.e., condensed matter with both piezoelectric and ferromagnetism. This MSHG is due to the coupling between a piezoelectric structure of F (4) over bar 3m and ferromagnetism with a T-C of 46 K.
