Synthesis and structures of new salen complexes with bulky groups

A new series of Schiff base complexes [Fe(III), VO(II), Pd(II), Cu(II), and Ni(II)] has been developed. The ligand possesses bulky t-pentyl groups at the 3- and 5-positions. The iron (III) complex is obtained in monomeric form with a square-pyramidal configuration while the copper complex is with square-planar configuration.

A new series of salen metal complexes has been prepared to possess bulky groups in the periphery of the ligand. Iron complex obtained is monomeric and has a square-pyramidal configuration.Figure optionsDownload as PowerPoint slide
