A new Fe(iii) complex (F1), structurally characterised using single crystal X-ray studies, was explored for CO2 fixation, Zn2+ recognition and catecholase activity.

A bis‐imine derivative is used for the synthesis of a dinuclear Fe(III) complex (F2) in presence of azide ion, the structure of which is confirmed by single crystal X‐ray diffraction analysis. The F2 selectively recognizes F− via turn on fluorescence at micro‐molar level. In presence of F−, non‐fluorescent F2 assumes an average life time, 1.17 ns. In addition, preliminary studies on catalytic efficiency of F2 for fixation of atmospheric CO2 by transforming epoxide to cyclic carbonate is impressive with almost 99 % yield under optimum conditions.

An imine derivative, N,N'-bis-(2-hydroxo-3-ethoxy-benzylidene)cyclohexane-1,2-diamine have been explored for the synthesis of a new Fe(III) complex (F3), the structure of which is confirmed by single crystal X-Ray diffraction ( SC-XRD) analysis. The F3 is very sensitive for selective optical recognition ofThe interaction of F3 with H 2 PO 4 À allows nano-molar (91.17 nM) level detection of H 2 PO 4 À having association constant, 6.92 × 10 4 M À 1 . In addition, F3 is found to have an efficient anti-cancer activity against human breast cancer cell line MCF7 and MDA-MB-231.
