In order to develop a highly- effective antitumor drug of retinoic acid,a new complex of nickel with all-trans retinoic acid has been synthesized in absolute ethanol,without oxygen in darkness and characterized by elemental analysis,molar conductance,IR,UV,and HNMR spectrometry. Its formula is best described as Ni2 .3H2O.

为了开发一种新型高效的维甲类抗癌新药，在无水、无氧、避光条件下合成了维甲酸镍的配合物，通过元素分析、摩尔电导、红外光谱、紫外光谱、差热及核磁共振氢谱测定了配合物的组成、结构和性质，其分子式为Ni2 。3H2O。

Similarly, molecular formulas have to have subscripts after the element name, not before.

类似的，分子式中的下标是在元素符号后边的，而不是前边。

A formula contains the symbols of the kinds of atom in the each molecule and subscripts that indicate the number of each kind of atom in the molecule.

分子式中含有原子符号，下标的数字表示分子中每种原子的数量。
