Synthesis, Characteristics, and EPR Study of Mn(II) and Cu(II) Chelates with a Product of Condensation of 2-(7-Bromo-2-oxo-5-phenyl-3Н-1,4-benzodiazepin-1-yl)acetohydrazide and 2,3-Dioxoindole

Abstract

The [Mn(HydrHIz)₂] ∙ 2H₂O (I) and [Cu(HydrHIz)₂] (II) complexes (HydrHIz is a hydrozone—the product of condensation of hydrazide and isatin) have been synthesized through self-assembly in the М(СН₃СОО)₂–2-(7-bromo-2-oxo-5-phenyl-3Н-1,4-benzodiazepin-1-yl)acetohydrazide (Hydr)–2,3-dioxoindole (HIz)–propan-2-ol systems (М = Mn, Cu). The complexes have been characterized by elemental analysis, electrical conductivity, and IR spectroscopy data. The composition and structure of the coordination cores in I and II have been determined by magnetic susceptibility and EPR spectroscopy methods.
