First example of a dumbbell-like architecture containing M3L2 cages and terephthalate anions
Abstract
A novel complex [Ag3(titmb)2]2[1,4-C6H4(COO)2]3·23 H2O [titmb = 1,3,5-tris(imidazol-1-ylmethyl)-2,4,6-trimethylbenzene] contains two M3L2 cages and three terephthalate anions, one of which is embedded in the two cages to form a dumbbell-like architecture and shows photoluminescence in the solid state when the titmb reacts with [Ag(NH3)2]NO3, an individual M3L2 cage [Ag3(titmb)2][NO3]3·5 H2O without luminescent properties was obtained.
