High‐nitrogen‐content compounds 6‐azido‐1,2,4‐triazolo[4,3‐b]pyridazine (C₅H₃N₇) and its 3‐methyl derivative (C₆H₅N₇) have been in situ crystallized in a diamond‐anvil cell and their structures determined by single‐crystal X‐ray diffraction. Under ambient and high‐pressure conditions the crystallizations yield the same phases: the C₅H₃N₇ anhydrate and C₆H₅N₇ hydrated clathrate. In both the structures there are clearly distinguished regions of short CH…N and N…N intermolecular contacts, the latter involving exclusively the azide groups. High pressure initially increases the contents of water in the channel pores of the clathrate.

通过CH…N和N…N相互作用进行晶体设计：高氮含量的叠氮基-三唑并哒嗪化合物的高压结构

高氮含量的化合物-6-叠氮基-1,2,4-三唑并[4,3- b ]哒嗪（C ₅ H ^ ₃ Ñ ₇）和它的3甲基衍生物（C ₆ H ^ ₅ Ñ ₇）已经在在金刚石-砧室中原位结晶，并通过单晶X射线衍射确定其结构。在环境和高压条件下，结晶产生相同的相：C ₅ H ₃ N ₇无水物和C ₆ H ₅ N ₇水合包合物。在这两种结构中，都有明显的CH…N和N…N分子间短接触区域，后者仅涉及叠氮化物基团。高压最初会增加包合物通道孔中的水含量。
