Abstract:
In the title compound, C18H16ClNO2S, the thia-zole ring subtends dihedral angles of 13.12 (14) and 43.79 (14) ° with the attached chloro-phenyl and phenyl rings, respectively. In the crystal, C-H⋯π inter-actions link the mol-ecules, forming a three-dimensional network. The roles of the various inter-molecular inter-actions were clarified by Hirshfeld surface analysis, which reveals that the most important contributions to the crystal packing are from H⋯H (39.2%), H⋯C/C⋯H (25.2%), Cl⋯H/H⋯Cl (11.4%) and O⋯H/H⋯O (8.0%) contacts.

Crystal Field Theory - Tetrahedral and Square Planar Complexes
Crystal field theory (CFT) is applicable to molecules in geometries other than octahedral. In octahedral complexes, the lobes of the dx2−y2 and dz2 orbitals point directly at the ligands. For tetrahedral complexes, the d orbitals remain in place, but with only four ligands located between the axes. None of the orbitals points directly at the tetrahedral ligands. However, the dx2−y2 and dz2 orbitals (along the Cartesian axes) overlap with the ligands less than the dxy,...
