- Abstract
Two two‐dimensional and three‐dimensional supramolecular complexes [M (L)2] (NO3)2·2CH3OH (M = Cu(1) and Co(2), L = 2‐(4‐imidazolyl)‐4‐methyl‐1,2‐quinazoline‐N3‐oxide), were synthesized and characterized by FT‐IR and UV–Vis spectroscopy, as well as elemental analysis. The spectroscopic data of both complexes were compared with the ligand L. Both complexes were determined by X‐ray single‐crystal diffraction and display similar coordination geometry and have a 2:1 ligand‐to‐metal ratio. All the central M (II) atoms are hexa‐coordinated with perfect octahedral geometries. In the crystal structures, complexes 1 and 2 form an infinite 1‐D chain‐like and 2‐D, 3‐D supramolecular frameworks. X‐ray photoelectron spectrum (XPS) and thermal stability of 2 was investigated. Moreover, electrochemical properties and antimicrobial activities of both complexes were also studied.

The spectroscopic data of complexes were compared with L. Both complexes were determined by X‐ray single‐crysta diffraction and display perfect octahedral geometries. In the crystal structures, complexes 1 and 2 form an infinite 1‐D chain‐like and 2‐D, 3‐D supramolecular frameworks. XPS and thermal stability of 2 was investigated. Electrochemical properties and antimicrobial activities of complexes were also studied.
