Abstract

The complexation of a julolidine-quinoline based tridentate ligand with three oxo-metal ions, dioxovanadium(V), oxo-rhenium(V) and dioxo-uranium(VI), has been investigated with four new complexes being synthesised and structurally characterised. (VO2L)"¢2/3H2O (1) {HL (C22H21N3O) = ((E)-9-((quinolin-8- ylimino)methyl)-1,2,3,5,6,7-hexahydropyrido[3,2,1-ij]quinolin-8-ol)} has a VO2L neutral mononuclear structure with a five-fold coordinated vanadium metal centre in a distorted trigonal bipyramidal geometry. (ReOL2)2(ReCl6)"¢7DMF (2) [DMF = dimethylformamide] exhibits a mixed valent rhenium complex with a (ReOL2)+ cationic unit in a distorted octahedral metal coordination geometry, charge balanced with (ReCl6)2 Ì… anions. [(UO2)L(H2O)2]2"¢2(NO3)"¢HL"¢4H2O (3) and [(UO2)L(CH3OH)2](NO3)"¢CH3OH (4) both have (UO2L)+ cationic mononuclear structures with either coordinated water or methanol molecules in pentagonal bipyramidal coordination geometries for the uranium metal centres. Intra-/intermolecular interactions including hydrogen bonding and Ï€-Ï€ interactions are common and have been discussed. In addition, optical absorption and photoluminescence properties have been investigated.
