pH dependent synthesis of Zn(<scp>ii</scp>) and Cd(<scp>ii</scp>) coordination polymers with dicarboxyl-functionalized arylhydrazone of barbituric acid: photoluminescence properties and catalysts for Knoevenagel condensation

Abstract

Coordination polymers of Zn(<sc>ii</sc>) and Cd(<sc>ii</sc>) act as recyclable heterogeneous catalysts for Knoevenagel condensation reaction of aldehydes with malononitrile.
