Annotation: One of the important areas of modern coordination chemistry is the synthesis and study of complex compounds of transition metals with biologically active ligands. The development of new highly effective biologically active drugs is one of the tasks of modern medicine and agriculture. The directed synthesis of coordination compounds of biometals with physiologically active organic compounds can be of great help in solving this problem.

Keywords: transferable ligand complexes, coordination, anisotropic spectrum, g-factor, quaternary metallocycles, bidentate coordination.
