Abstract
In the title compound, C25H22O, the two rings of the naphthalene system are inclined to each other by 3.06 (15)°. The mean plane of the naphthalene ring system makes a dihedral angle of 65.24 (12)° with the di-methyl-phenyl ring and 55.82 (12)° with the meth-oxy-phenyl ring. The di-methyl-phenyl ring is inclined to the meth-oxy-phenyl ring by 59.28 (14)°. In the crystal, adjacent mol-ecules are linked via C-H⋯π inter-actions, forming chains along [100]. Using Hirshfeld surface and two-dimensional fingerprint plots, the presence of short inter-molecular inter-actions in the crystal structure were analysed. The inter-molecular inter-action energies were also calculated and their distribution over the crystal structure was visualized graphically using energy frameworks.
Highlights
Naphthalene and its derivatives are known for their wide range of applications in the field of pharmaceuticals
The bond lengths and bond angles are similar to those reported for 1,4-diphenylnaphthalene, which crystallized with two independent molecules in the asymmetric unit (Lima et al, 2012)
Supramolecular features In the crystal, there is only one significant intermolecular interaction present, viz. a C—HÁ Á Á interaction linking adjacent molecules to form chains propagating along the a-axis direction (Table 1 and Fig. 2)
Summary
Naphthalene and its derivatives are known for their wide range of applications in the field of pharmaceuticals. They are used in the manufacturing of colorants, surface-active agents, resins, disinfectants and insecticides. These derivatives play a vital role in the control of microbial infection (Rokade & Sayyed, 2009) and in the chemical defence against biological enemies (Wright et al, 2000). Compounds with a naphthalene moiety have been shown to exhibit significant anti-TB activity (Upadhayaya et al, 2010)
