Key Points

The compound features a distorted octahedral geometry, with cadmium(II) coordinated to a bidentate ligand and azide ions.
Cadmium(II) forms zigzag polymeric chains linked by bridging azide ions in a unique μ1,1 coordination.
Hirshfeld surface analysis quantifies the critical intermolecular interactions present in the structure.
Understanding the formation of layers through hydrogen bonds provides insight into structural stability.

Abstract

In the title compound, Cd(N3)2(C10H9N3) n , the cadmium(II) ion displays a distorted CdN6 octa-hedral geometry arising from one bidentate ligand and four azide ions and forms zigzag polymeric 100 chains via the bridging azide ions, both of which show μ1,1 (end-on) coordination. Adjacent chains are linked into layers via N-H⋯N hydrogen bonds. Hirshfeld surface analysis was used to qu-antify the inter-molecular inter-actions.
