老师您好!我在投稿时编辑问了一个这样的问题,Are their no restraints for the ‘riding’ hydrogens
我周围没有人专门做晶体,请问老师这是什么意思,该从那些方面回答那

老师您好!
现在编辑主要是对文章中晶体数据Data / restraints / parameters   3969 / 0 / 305进行发问pag 9 23 Are their no restraints for the ‘riding’ hydrogens? 这是我单晶结构的描述部分,我没有进行限制只是进行了理论加氢。我该怎么解释那
The crystallographic data for complexes 1 was collected on a Bruker Smart 1000 CCD area detector
diffractometer equipped with Mo Kα (λ = 0.71073 Å radiation using ω-scan mode. Empirical
absorption correction was applied to the data. Unit cell dimensions were obtained with least-squares
refinements, and all structures were solved by direct methods with SHELXL–97. All non-hydrogen
atoms were located from the trial structure and then refined anisotropically. All hydrogen atoms were
generated in idealized positions. All calculations were performed with SHELXL-97 programs [22].
Other relevant parameters of the crystal structure are listed in Table 1.
