The triple-decker complex [Yb3L3(OAc) 2Cl](H2O)3(CH3OH) 1.5(CH3CN)0.5 (1) is formed from the reaction of H2L, YbCl3·6H2O, and Zn(OAc) 2·2H2O in 25% yield (H2L = N,N′-bis(5-bromo-3-methoxysalicylidene)phenylene-1,2-diamine). The single-crystal X-ray structure of 1 revealed the presence of two independent, chiral molecules of 1 in the asymmetric unit. Intermolecular π-π stacking and C-H·π interactions between both sets of Yb3L 3 units create two one-dimensional strands, A and B. Strands of A are cross-linked via Br⋯H-C hydrogen bonds creating a three-dimensional network that encloses the B strands. Near-infrared (NIR) lanthanide luminescence in both the solid state and the solution is observed in 1.
