Several salicylatocopper(II) complexes with diethylnicotinamide: Preparation, structure, spectral properties and Hirshfeld surface analysis

Synthesis and crystal structure of a new copper (II) complex, designed to produce efficient successor of Cu2O, toward synergy of adsorption and photodegradation of MB

“…The Cu 2+ is bonded to four nitrogen atoms and two oxygen atoms forming an octahedral geometry (in site Figure ). The Cu‐N distance has the average of 2.019 Å in good agreement with the value of reported Cu‐N bond lengths for azo‐copper complexes 45–47 . The Cu‐O distances have the values of 2.314(2) and 2.400(2) Å for Cu1‐O1 and Cu1‐O3 respectively, which are similar to those presented in copper carboxylate ligand complexes 46, 47 .…”

The bond angles of N‐Cu‐N have the range between 81.14 (9)° and 177.15(10)°, and for N‐Cu‐O are in the range of 74.62(9)° ‐112.04(10)° while the O1‐Cu1‐O3 exhibits a bond angle of 150.30 (8)°, all these values of angles are also similar to the values reported for azo‐carboxylate‐copper complexes 45, 47 .…”

In the crystal packing, the structure is built up of a discrete layers formed by the interaction alone a axis between the complexes via hydrogen bonds (Figure ).…”
