Background:
- The compound C(17)H(14)N(2)S(2) is a novel organic molecule containing benzothiazole moieties.
- Understanding the solid-state structure and molecular geometry is crucial for predicting material properties and reactivity.
Purpose of the Study:
- To elucidate the crystal structure and molecular geometry of C(17)H(14)N(2)S(2).
- To compare the geometric parameters of the two symmetry-independent molecules within the crystal lattice.
Main Methods:
- Single-crystal X-ray diffraction was employed to determine the three-dimensional structure.
- Least-squares planes were calculated for the benzothiazole groups to analyze their spatial arrangement.
Main Results:
- The asymmetric unit contains two symmetry-independent molecules of C(17)H(14)N(2)S(2).
- Both molecules exhibit similar overall geometry.
- The dihedral angles between the benzothiazole least-squares planes are 83.93(3)° and 81.26(3)°.
