Water-soluble chiral coordination polymers of Li+, Na+, K+, and Ba2+ with an anionic iron(iii) complex of a l-threonine derivative and a significant red shift of visible spectra with Al3+ salt

Abstract

Four chiral water-soluble coordination polymers of an anionic iron(iii) bis-complex and metal cations were synthesized from water or methanol. The addition of Al3+ salt to Na+ complex showed an unexpected colour shift.
