Reaction of copper(I) halides with chiral dithiodianthranilidesmdtaandbdtaafforded polymeric complexeswhere polynuclear CuX clusters were linked together by ditopic bridging ligands into 1D chains or 2D layerstructures. In the case of racemic ligands double stranded chain polymers were formed where the Cu4X4(X = I or Br) cores are connected by enantiomeric pairs of the ditopic ligands. In contrast, a homochiralmdtaligand created a single stranded hybrid chain involving singlemdtaenantiomers and solvated Cu5I5clusters or 2D square (4,4) nets composed of rings comprising four Cu3X3clusters in nodes and fourhomochiral ligand molecules in sides with solvent MeCN molecules between the grid layers. The hybridlayer structure obtained from CuCl and the racemicmdtaligand crystallized as a conglomerate that led toits self-resolution into enantiomeric chiral crystals. The solid state CD spectra revealed contribution of twoelectronic transitions to the diffuse lowest energy absorption band of the complexes. In addition theobserved long wavelength Cotton effect sign reflected the helicity of the thiobenzamide chromophore inthe ligand unit. At room temperature the solid complexes exhibited weak red phosphorescence near 600–620 nm. Upon cooling down to 10 K all investigated complexes are phosphorescent with average lifetimesof 17–84μs.
