To study the interaction of 2,6-pyridinedicarboxylic acid (2,6-PDCA) with metal ions and the properties of its metal complexes, a new complex product with cobalt(II) acetate and monoethanolamine in a 1:2:2 M:L:L ratio and a coordination number of six was synthesized and grown as a single crystal. The composition and structure of the complex were determined using X-ray. In the complex product, the 2,6-pyridinedicarboxylic acid ligand is coordinated in the tridentate state. The Hirshfeld surface was analyzed using Crystal Explorer 17.5. The IR spectrum of the crystal of the complex compound was analyzed, and the vibration frequencies of the corresponding bonds were determined.
