Abstract:
The title compound, C19H17NO5, obtained by ether bond formation between the reagents, crystallizes in the monoclinic space group P21/c. The compound is non-planar, subtending a dihedral angle of 82.38 (4)° between the plane of hy-droxy isophthalate-based ester and that of the benzo-nitrile moiety. The mol-ecule is bent at the ether linkage, with a Car-yl-O-Car-yl bond angle of 116.74 (11)°. In the crystal, mol-ecules are linked by C-H⋯O hydrogen bonds and other weak inter-actions forming a supra-molecular framework. A Hirshfeld surface analysis was performed to generate two-dimensional fingerprint plots, which reveal the type of inter-actions occurring in the vicinity of the mol-ecule.

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...

Structure of Conjugated Dienes
Conjugated dienes are compounds characterized by the presence of alternating double and single bonds. In a conjugated system like 1,3-butadiene, the unhybridized 2p orbital on each carbon overlaps continuously, allowing the π electrons to be delocalized across the entire molecule. In contrast, this type of overlap does not occur in cumulated and isolated dienes, such as 2,3-pentadiene and 1,4-pentadiene, respectively. Instead, the π electrons remain localized between the double...
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,...
