Highly Efficient Synthesis of Complex bis-2,4-dimethoxy-1,3,5-triazapentadienemetal(II) (metal = Cu, Ni) with Hirshfeld Surface Analysis

Abstract

The synthesis of copper(II) or Nickel(II) complex with bis-2,4-dimethoxy-1,3,5-triazapentadiene ligand has been reported using a direct reaction and reflux method. These methods take a relatively long synthesis time, so it is necessary to develop a faster synthesis method. This study reports a solvothermal method to synthesize bis-2,4-dimethoxy-1,3,5-triazapentadiene copper(II) and nickel(II) as in situ with sodium dicyanamide and methanol that produces single crystals in a day and two days respectively. XRD analysis of both single crystals from solvothermal results showed a monoclinic crystal lattice and a P21/n space group which was not different from previous studies. The Hirshfeld analysis indicates that the interactions with the most prevelant contributions in both of complexes are H—H, O—H/H—O, and N—H/N—H.
