Six copper(II) complexes of 2-hydroxy-4-methoxybenzaldehyde nicotinoylhydrazone (H2hmbn), 2-hydroxy-4-methoxyacetophenone nicotinoylhydrazone (H2hman), 2-hydroxy-4-methoxybenzaldehyde benzoylhydrazone (H2hmbb) and 2-hydroxy-4-methoxyacetophenone benzoylhydrazone (H2hmab) have been synthesized. The complexes viz. [Cu(hmbn)]2·2H2O (1), [Cu(hman)]2 (2), [Cu(hmbb)]2·2H2O (3), [Cu(hmbb)phen]·1(1/2)H2O (4), [Cu(hmbb)(bipy)·H2O] (5) and [Cu(hmab)phen] (6) were characterized by different physicochemical techniques. The crystal structure of [Cu(hman)phen] is obtained and it has a distorted square pyramidal geometry with π–π stacking interactions and significant C–H π interactions.
Graphical abstractA new series of copper(II) complexes of four different acylhydrazones have been prepared and their spectroscopic and structural characterization described. One of the crystal structures of synthesized copper complexes has a distorted square pyramidal geometry with strong π–π stacking and C–H⋯π interactions in its packing.Figure optionsDownload full-size imageDownload as PowerPoint slideHighlights► Six copper(II) complexes are synthesized by using H2hmbn, H2hman, H2hmbb and H2hmab. ► A crystal structure of one of the complexes, [Cu(hman)phen] is obtained. ► Coordination geometry of the complex [Cu(hman)phen] is distorted square pyramid. ► The π–π interaction plays an important role in controlling the packing of compounds. ► C–H⋯π interactions and intermolecular hydrogen bonding are also present.
