Abstrakt: A detailed study of the soft X-ray photochemistry occurring in some nickel dithiocarbamate and xanthate complexes has shown that soft X-ray induced photoreduction of [NiIV(S2CNEt2)3][BF4] results in a NiII square-planar species and the rate is dependent on photon flux, photon energy and ligand set, but is essentially independent of temperature. Also, it has been demonstrated that [PPh4][NiII(S2COEt)3] is photoisomerised to a NiII square-planar species on exposure to soft X-rays. The implication for experiments on third generation synchrotron sources is discussed briefly.
