4,5-Dicarboxynaphthalene-1,8-dicarboxylic anhydride–1,10-phenanthroline (1/1)

چکیده
In the crystal structure of the title 1:1 adduct, C(12)H(8)N(2)·C(14)H(6)O(7), the carboxyl groups are involved in inter-molecular O-H⋯O hydrogen bonds, which link the mol-ecules into centrosymmetric dimers. These dimers are further linked by inter-molecular O-H⋯N hydrogen bonds. C-H⋯O inter-actions also occur between the 1,10-phenanthroline (phen) and 4,5-dicarb-oxy-naphthalene-1,8-dicarb-oxy-lic anhydride (H(2)NTC) mol-ecules. In addition, the crystal structure exhibits π-π inter-actions of the phen⋯phen and H(2)NTC⋯H(2)NTC types with centroid-centroid distances of 3.579 (3) and 3.774 (3) Å, respectively.
