Abstract

Abstract : A new Fe(iii ) complex (F1 ), structurally characterised using single crystal X-ray studies, was explored for CO2 fixation, Zn 2+ recognition and catecholase activity. Abstract : A dinuclear Fe(iii ) complex (F1 ) of an imine derivative (L1 ) derived from 3-ethoxy-2-hydroxy-benzaldehyde and hydrazine, structurally characterised via single crystal X-ray studies, is employed for the catalytic conversion of epoxides to cyclic carbonates utilizing carbon dioxide. In addition, F1 is employed for the selective optical recognition of nano-molar levels of Zn 2+ (42.23 nM) via a metal displacement approach. The Job plot reveals interactions between F1 and Zn 2+ at a 1 : 3 molar ratio with an association constant of 7.71 × 10 4 M −1 . Studies on the catecholase-like activity of F1 reveal a k cat value of 4.42 × 10 3 h −1 .
