[1‐(Pyrazin‐2‐yl)ethylidene]hydrazine: a new multitopic ligand for the design of hybrid molecular frameworks

摘要

Hydrazones and their derivatives are closely related to imine compounds and are potential antimicrobial agents. They have also found application in supramolecular chemistry as multitopic ligands to link multiple metal centres for the design of hybrid molecular frameworks. The molecule of the title compound, C 6 H 8 N 4 , consists of an imine linkage with an N—N bond length of 1.3540?(14)??. This asymmetric compound is nearly planar and adopts an E configuration about the azomethine C=N double bond. In the solid state, there are two intermolecular N—H…N interactions that interconnect the molecules into a two‐dimensional network. The three‐dimensional arrangement of the crystal packing is further stabilized by intermolecular π–π interactions interconnecting the centroids of the heterocyclic rings.
