Abstract:
In the title compound, C(19)H(24)N(2)O(4)S(2), the dihedral angle formed by the benzene rings is 82.88 (7)°, and the mol-ecular conformation is enforced by weak intra-molecular C-H⋯O contacts. Two C atoms of the 1,4-diazepane ring are disordered over two sets of sites with a refined occupancy ratio of 0.534 (13):0.466 (13). In the crystal, mol-ecules are linked by weak inter-molecular C-H⋯O inter-actions into chains parallel to the a axis.

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...
