Syntheses and structures of two anthracene–benzoic acid derivatives as potential MOF linkers
In the title compounds, 2,2'-{[anthracene-9,10-diylbis(methyl-ene)]bis-(sulfane-di-yl)}di-benzoic acid di-methyl-acetamide tetra-solvate, C<sub>30</sub>H<sub>22</sub>O<sub>4</sub>S<sub>2</sub>·4C<sub>4</sub>H<sub>9</sub>NO <b>1</b> and 4,4'-{[anthracene-9,10-diylbis(methyl-ene)]bis-(-oxy)}di-benzoic acid di-methyl-formamide disolvate, C<sub>30</sub>H<sub>22</sub>O<sub>6</sub>·2C<sub>3</sub>H<sub>7</sub>NO <b>2</b>, 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 <b>1</b> and 75.27 (12)° in <b>2</b>. In the extended structures of <b>1</b> and <b>2</b>, 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.
