A set of (Ln[14-MC-5])LnZn(quinHA)(ph)(Hph)(OH)(HO) metallacrowns (, Ln = Tb, Gd, or Yb; HquinHA = quinaldic hydroxamic acid, Hph = phthalic acid) have been synthesized via solution-state self-assembly. The metallacrowns possess an uncommon topology within the metallacrown family where two rarely seen 14-metallacrown-5 moieties are fused by a YbZn(quinHA) bridge. Moreover, analyzed in the solid state exhibits a characteristic near-infrared luminescence signal arising from Yb F→F transition despite the proximity of high energy O-H oscillators.
