Dimethylsulphoxide (DMSO) may act as a potent medium for electrodeposition of Ni in presence of nucleosides. Totally bright electroplate may result from NiAc+NiSO4+NiSMT/DMSO bath in presence of trace amount of nucleoside (ribocytine/deoxycitidine). Too many coordinating centers of nucleoside facilitate the release of Ni from [Ni(DMSO)(6)](3+) complex in the vicinity of catholite causing outwardly growth more dominant than lateral growth, resulting in bright. adherent, Ni electrodeposite.
