Synthesis and antimicrobial properties of lipophilic Schiff base copper and palladium complexes

Abstract

The reaction of Cu(II) sulfate or Pd(II) acetate with four salicylaldimines derived from 5-bromosalicylaldehyde and long-chain aliphatic primary amines afforded the corresponding metal complexes 2a–d and 3a–d, respectively. All complexes were characterized by physicochemical and spectroscopic methods. The molecular structure of 2b was determined by a single-crystal X-ray diffraction study. All complexes were tested for their potential antifungal and antibacterial activities.
