Experimental and theoretical study of photoluminescence and magnetic properties of metal–organic polymers based on squarate and tetrazolate moieties containing linkers

Abstract

We report on the synthetic, luminescence and magnetic properties of three new isostructural Zn-, Cd- and Co-based 1D coordination polymers with the novel 3-(1H-tetrazol-5-ylamino)-4-hydroxycyclobut-3-ene-1,2-dione spacer, consisting of a squarate and a tetrazolate moiety linked by a NH group. These compounds exhibit an intense blue-green photoluminescence emission at room temperature in the solid state (Cd- and Zn-based structures) and antiferromagnetic exchange interactions (Co-based materials).
