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^{-{radical dot}})]⁺ due to the outer-sphere electron transfer.
