文摘

The octahedral copper(II) complex with two 2′‐[1‐(2‐pyridinyl)ethylidene]oxalohydrazide molecules was synthesized from bis(acetylacetonato)copper(II) and 2′‐[1‐(2‐pyridinyl)ethylidene]oxamohydrazide (Hapsox). The complex is unstable when not in solution. X‐ray analysis confirmed the tridentate coordination of the ligands in the monoanionic form. In addition, the stable tetrahedral copper(II) complex with one ligand molecule coordinated as a tridentate in the dianionic form was prepared by direct synthesis from Cu(NO₃)₂·3H₂O and Hapsox, and characterized by elemental analysis, magnetic measurements and by i.r. and u.v./vis. spectrophotometry.
