Binary charge-transfer complexes using pyromellitic acid dianhydride featuring C-H?O hydrogen bonds.

ABSTRACT: Four binary charge-transfer complexes were made using pyromellitic acid dianhydride (pmda), those being pmda-naphthalene (1/1), C10H2O6·C10H8, (I), pmda-fluoranthene (1/1), C10H2O6·C16H10, (II), pmda-9-methyl-anthracene (1/1), C10H2O6·C15H12, (III), and pmda-ethyl anthracene-9-carboxyl-ate (1/2), C10H2O6·2C17H12O3, (IV). All charge-transfer complexes show alternating donor and acceptor stacks, which have weak C-H?O hydrogen bonds connecting the donor and acceptor mol-ecules. In addition, complex (I) has Z' = 1/2, complex (II) has a Z' = 2 and complex (IV) has half mol-ecule of pyromellitic acid dianhydride in the asymmetric unit.
