Synthesis and Selected Properties of Novel Metal Complexes with Bis-Azomethine Based on 7-Hydroxy-4-methyl-8-formylcoumarin and 1,3-Diaminopropan-2-ol

Condensation of 7-hydroxy-4-methyl-8-formylcoumarin with 1,3-diaminopropan-2-ol has afforded a novel bis-azomethine, and its metal chelates with copper(II), nickel(II), and zinc(II) have been obtained. Structure and properties of the prepared compound have been studied by spectral and quantum-chemical methods.
