Abstract:
The asymmetric unit of the title compound, C16H12ClN3S, contains two independent mol-ecules whose conformations differ primarily in the orientations of the phenyl and chloro-benzene rings with respect to the thia-zole ring. In the first mol-ecule, the dihedral angles are 3.0 (1) and 9.2 (1)°, respectively, for the phenyl ring and the chloro-benzene ring, while in the second mol-ecule, the corresponding angles are 18.6 (1) and 23.4 (1)°. In the crystal, the two independent mol-ecules are associated via complementary N-H⋯N hydrogen bonds into a dimer. These dimers are associated through weak C-H⋯Cl and C-H⋯S inter-actions into supra-molecular chains propagating along the a-axis direction.

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...
Ionic Crystal Structures
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...
