Photochemical oxidative addition of hydrazinium cations to tetracyanoplatinate(II) induced by OSCT excitation

The hydrazinium cations N2H62+/N2H5+ form ion pairs with [Pt(CN)4]2−. Outer-sphere charge transfer excitation (PtII → image/image) induces an oxidative addition: image/image image → [PtIV(CN)4(NH3)2] and [Pt(CN)4(NH3)(NH2)], respectively.
