A new ladder-type dichloro(2,2-dimethyl-1,3-diaminopropane) copper complex: Synthesis, structural studies and selective sensing behavior towards a ketone molecule

Abstract

A new coordination compound with the formula [Cu(dmpd)Cl2], where dmpd stands for 2,2-dimethylpropane-1,3-diamine, was prepared and structurally characterised by elemental analyses, IR and UV/Vis spectroscopic studies. The single crystal X-ray crystallographic study revealed the copper cation to be six coordinated in the complex by two amine nitrogen atoms and four chloride ions. The copper atom adopts a distorted tetragonal bipyramidal geometry, with two bridging chloride ions located at the polyhedron apexes. Furthermore, to obtain insight into the structure, theoretical studies were performed. The complex exhibits a strong photoluminescence property in tetrahydrofuran and shows a strong sensing behaviour towards a ketone molecule, proving it to be a good candidate for sensing measurements.
