Network of C-H...O interactions in 1,2-naphthalenedicarboxylic anhydride
1Department of Chemistry, Ohio State University, Columbus 43210, USA.
Abstract:
The title substance, C12H6O3, crystallized in the centrosymmetric space group P2(1)/c with one molecule in the asymmetric unit. Four significant C-H...O interactions have C...O distances ranging from 3.313 (2) to 3.453 (2) A. They link each molecule directly to eight neighbors, generating a three-dimensional network. The anhydride group is compared with those in phthalic anhydride and 1,4,5,8-naphthalenetetracarboxylic 1,8:4,5-dianhydride.
