An environmentally benign protocol for the synthesis of azo Schiff bases and its complex in short reaction time and high yield has been achieved. These Schiff base compounds have been characterized by C, H, N elemental analyses, FT-IR and 1 H NMR spectroscopy. The synthesized complex was characterized by atomic absorption spectrophotometry and elemental analyses. EXPERIMENTAL Materials and instruments For the ultrasound reactions, ultrasound apparatus astra 3D (9.5 dm 3 , 45 kHz frequency,
