Promotion of a synthon of choice for the non-covalent assembly of lanthanide tectons represents both a noteworthy challenge and opportunity within Ln(III) hybrid materials. We have developed a system wherein some control can be exercised over supramolecular assembly and, as part of continued efforts to improve this process we have generated a family of ten new lanthanide (Ln = Sm3+-Lu3+)-2,4,6-trichlorobenzoic acid-1,10- phenanthroline molecular complexes. Delineation of criteria for promoting assembly via halogen based interactions was introduced previously and is refined herein based on the characterization of complexes 1-10 via single crystal X-ray diffraction. Direct comparison of means of supramolecular assembly for 1-10 with isostructural Ln-pchlorobenzoic acid-1,10-phenathroline analogues verifies that increasing the number of halogens at the periphery of a tecton is one route that increases the frequency of halogen bonding interactions. Additionally, solid-state visible and near-IR photoluminescence and luminescent lifetime data were collected for complexes 1 (Sm3+), 2 (Eu3+), 4 (Tb3+), 5 (Dy3+), 6 (Ho3+), 7 (Er3+), and 9 (Yb3+) and characteristic emission was observed for all complexes except 6. Further, direct current magnetic susceptibility measurements were carried out for complexes 5 (Dy3+) and 7 (Er3+), and two slow magnetic relaxation processes were characterized using alternating current magnetic susceptibility measurements for 5.
