Analytical, Infrared, 1 HNMR, Mass, and UV-Visible spectral information have been used to perform a basic structural interpretation of the ligand and metal complexes.

Introduction Among several naturally occurring compounds, napthofuran derivatives are one of them. Several biological compounds that contain the napthofuran ring have a broad range of biological effects, notably anthelmintic, anticonvulsant, and antipyretic effects.[1,2]. “Napthofuran is one of many important molecules that, when condensed with other
