Abstract
Ionic triads formed by [Ni II(bipy) 3] 2+ (bipy = 2,2′-bipyridyl) and diamagnetic [M IV(CN) 8] 4− (M = Mo and W) were prepared and structurally characterized. The two compounds are isostructural and their structure consists of a three-dimensional hydrogen-bonded framework where cation–anion interactions occur through short contacts M–CN⋯H–C(bipy). Before irradiation, the Mo analogue behaves as paramagnet with small intermolecular interactions between the [Ni II(bipy) 3] 2+ cations. Upon irradiation with visible light, it exhibits a reversible photomagnetic effect, which is interpreted in terms of the formation of paramagnetic [Mo V(CN) 8] 3− and [Ni II(bipy) 2(bipy − )] + due to the outer-sphere electron transfer.
