Abstract:
The isomers 3,3'-(1,2-ethynediyl)bis(2-pyridone), (I), and 6,6'-(1,2-ethynediyl)bis(2-pyridone), (II), were designed to form a hydrogen-bonded pair through alignment of their complementary cyclic lactam moieties. Instead, an equimolar mixture of (I) and (II) dissolved in methanol produced crystals of 3,3'-(1,2-ethynediyl)bis(2-pyridone)-6,6'-(1,2-ethynediyl)bis(2-pyridone)-methanol (1/2/2), 0.5C(12)H(8)N(2)O(2) x C(12)H(8)N(2)O(2) x CH(4)O, in which one molecule of (I), situated at a center of symmetry, is hydrogen bonded to two molecules of (II) and to two molecules of methanol.
