Molecular (photo)switch: A W-Co photomagnetic discrete complex can be prepared through the self-assembly of preformed building blocks. [Co(bik)3][{W(CN)8}3{Co(bik)2}3]⋅2 H2O⋅13 CH3CN (see figure) exhibits a thermally-induced electron-transfer-coupled spin transition between the two states: Co(HS)(II)-W(V)↔Co(LS)(III)-W(IV). It also shows photomagnetic effects at low temperature.
