Binary charge-transfer complexes using pyromellitic acid dianhydride featuring C—H⋯O hydrogen bonds

Four binary charge-transfer complexes were made using pyromellitic acid dianhydride (pmda), those being pmda–naphthalene (1/1), C(10)H(2)O(6)·C(10)H(8), (I), pmda–fluoranthene (1/1), C(10)H(2)O(6)·C(16)H(10), (II), pmda–9-methyl­anthracene (1/1), C(10)H(2)O(6)·C(15)H(12), (III), and pmda–ethyl anthr...

Sumario:Four binary charge-transfer complexes were made using pyromellitic acid dianhydride (pmda), those being pmda–naphthalene (1/1), C(10)H(2)O(6)·C(10)H(8), (I), pmda–fluoranthene (1/1), C(10)H(2)O(6)·C(16)H(10), (II), pmda–9-methyl­anthracene (1/1), C(10)H(2)O(6)·C(15)H(12), (III), and pmda–ethyl anthracene-9-carboxyl­ate (1/2), C(10)H(2)O(6)·2C(17)H(12)O(3), (IV). All charge-transfer complexes show alternating donor and acceptor stacks, which have weak C—H⋯O hydrogen bonds connecting the donor and acceptor mol­ecules. In addition, complex (I) has Z′ = 1/2, complex (II) has a Z′ = 2 and complex (IV) has half mol­ecule of pyromellitic acid dianhydride in the asymmetric unit.
