Abstract:
In the title compounds, 2,2'-{[anthracene-9,10-diylbis(methyl-ene)]bis-(sulfane-di-yl)}di-benzoic acid di-methyl-acetamide tetra-solvate, C30H22O4S2·4C4H9NO 1 and 4,4'-{[anthracene-9,10-diylbis(methyl-ene)]bis-(-oxy)}di-benzoic acid di-methyl-formamide disolvate, C30H22O6·2C3H7NO 2, the complete anthracene-benzoic acid mol-ecule is generated by a crystallographic centre of symmetry. The dihedral angle between the anthracene ring system and the pendant ring is 71.43 (7) in 1 and 75.27 (12)° in 2. In the extended structures of 1 and 2, O-H⋯O hydrogen bonds link the main mol-ecules into pairs of solvent mol-ecules to generate trimers. Weak C-H⋯O and C-H⋯π inter-actions further consolidate both structures.

Structures of Carboxylic Acid Derivatives
Carboxylic acid derivatives contain an acyl group attached to a heteroatom such as chlorine, oxygen, or nitrogen. The carbonyl carbon and oxygen are both sp2-hybridized with an unhybridized p orbital.
The three sp2 orbitals of the carbonyl carbon form three σ bonds, one each with the carbonyl oxygen, the α carbon, and the heteroatom, whereas the other two sp2 orbitals of the carbonyl oxygen are occupied by the lone pairs. Further, the unhybridized p...
