[求助] 如何用ccdc以氢键为参数进行搜索,多谢!

In 1, the acid hydrazide moiety of INH is linked to a similar
group in another molecule in a head-to-head arrangement
forming an acid-hydrazide/acid-hydrazide homosynthon which
resembles the amide dimers in primary amides. There are only 54
crystal structures deposited in the CSD where one acid hydrazide
group is linked to another via homosynthon II (the CSD search
was made by restricting both the H-bond distances [N–H/O
distances in the range of 0.0–2.5?A] and only organic molecules
were considered) and it is worth mentioning that II is not found
in the crystal packing of INH itself.

想知道红线的部分是如何实现的,多谢!
