Le mieux connu est NiO(OH)2 qui est une poudre noire obtenue par oxydation de Ni(OH)2 avec du brome Br2 à moins de 20°C. A chaud, il se forme un hydroxyde mixte Ni3O2(OH)4. L'oxydation de solution alcaline de sulfate de nickel par l'eau de Javel (NaClO) donne un peroxyde noir de formule mal établie, mais voisine de NiO2·xH2O.
