摘要： 晶体学研究曾认为,分子式是Na[NiQ2(HQ)](CLO4)的结构并不含有钠而应为[H3O][NiQ2(HQ)](CLO4).相似地，稀土－Ni络合物[YQ(HQ)2][NiQ3](CLO4)也不含有钇而应为[H3O][Ni2Q3(HQ)3](CLO4).晶体结构描述的修正系根据文献报导的原子坐标计算结构因子所导出的结果.

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
