Synthesis, crystal structure and luminescence properties of a europium(III) complex with a new planar aromatic tridentate N3 ligand

Abstract

The new planar aromatic tridentate nitrogen ligand 2,4-bis(3,5-dimethylpyrazol-1-yl)-6-methoxy-1,3,5-triazine (L) has been synthesized and the crystal structure of [EuL(NO3)3(H2O)]·L revealed a mononuclear structure with a ten-co-ordinate metal centre; π–π stacking and hydrogen bonding between the co-ordinated and unco-ordinated L molecules sensitized EuIII luminescence.
