Abstract: The compound that had been crystallographically identified as Na[NiQ2(HQ)](ClO4)(HQ=8-hydroxyqu- inoline) contains no sodium,and instead is [H3O][NiQ2(HQ)](ClO4).The lanthanum-nickel complex [YQ(HQ)2][NiQ3](ClO4) that had been similarly identified contains no yttrium,and its formula is [H3O][Ni2Q3(HQ)3](ClO4)2.The revision of the description of the crystal structures was effected by an examination of the bond dimensions that were derived by calculating the structure factors from the published atomic coordinates.

Key words: Structure revision, Nickel(II) complex, Calculated structure factors
