Abstract
A new yttrium complex, [Y 2 (H 2 Dhbds) 3 (phen) 2 ]·[Y 2 (H 2 Dhbds) 2 (H 2 Thbs)(phen) 2 ] ( 1 ) (Na 2 H 2 Dhbds = 4,5-dihydroxy-1,3-benzenedisulfonic acid disodium salt; NaH 3 Thbs = 2,3,5-trihydroxy-1-benzenesulfonic acid sodium salt), has been synthesized and structurally characterized. Complex 1 consists of two dinuclear structural units bridged by H 2 Dhbds 2- and H 2 Thbs 2- ligands, where phen molecules act as N, N-bidentate ligands, chelating Y atoms. The dinuclear structural units are connected by π-π stacking interactions between phen molecules, generating a one-dimensional chain structure. In addition, complex 1 exhibits the broad fluorescent emission band at 365 nm, which originates from intraligand charge transitions.
