X-ray structure, hirshfeld surfaces and interaction energy studies of 2,2-diphenyl-1-oxa-3-oxonia-2-boratanaphthalene

Single crystal XRD structure of the title compound reveals that the molecule adopt non-planar structure. The molecule is puckered with the total puckering amplitude of (Q) = 0.368(3)Å. Crystals of the title molecules are interconnected by intermolecular O-H⋯O and C-H⋯O interactions to develop 1D chains extending infinitely along the crystallographic a-axis. The intermolecular interactions were explored by Hirshfeld surfaces and their associated fingerprint graphs are obtained which revealed that the H⋯H and H⋯C pairs of inter atomic contacts were pre-dominant in the crystal packing of title compound. The energy of intermolecular interactions are computed using the accurate energy density model of B3LYP/6-31 G(d,p).

Synthesis, mol-ecular structure and Hirshfeld surface analysis of (4-meth-oxy-phen-yl)[2-(methyl-sulfan-yl)thio-phen-3-yl]methanone

The title compound, C13H12O2S2, crystallizes in the triclinic space group P . The mol-ecular structure is substanti-ally twisted, with a dihedral angle of 43.70 (2)° between the 2-(methyl-sulfan-yl)thio-phene and 4-meth-oxy-phenyl rings. In the crystal, mol-ecules are linked through C-H⋯O inter-actions and form a bifurcated layer stacking along the b-axis direction and enclosing R 2 2(10) ring motifs. The phenyl rings are involved in π-π inter-actions with a centroid-centroid separation of 3.760 (2) Å. The Hirshfeld surfaces were studied and the contributions of the various inter-molecular inter-actions were qu-anti-fied.
