Abstract: A new yttrium complex, [Y2(H2Dhbds)3(phen)2]·[Y2(H2Dhbds)2(H2Thbs)(phen)2] (1) (Na2H2Dhbds = 4,5-dihydroxy-1,3-benzenedisulfonic acid disodium salt; NaH3Thbs = 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 H2Dhbds2- and H2Thbs2- 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.
