Crystal structure of (2E)-3-(2-thienyl)acrylic acid-benzene-1,2-diamine
Özet
The title compound, (2E)-3-(2-thienyl)acrylic acid-benzene-1,2-diamine, was synthesized by the reaction of 1,2-diaminobenzen and 3-(2-tienyl)acrylic acide in a dioxane solution. The compound crystallizes in the orthorhombic space group Pbcn; a = 24.610(5)Å, b = 7.588(5)Å, c = 11.289(5)Å, V = 2108.1(17)Å3 and Z = 8. The final R value is 0.047. The thiophene and benzene ring are each essentially planar. The benzene-1,2-diamine moity in the title compound has a rotation axis that passes through the mid point of the bonds C8-C8a and C10-C10a. The crystal packing is stabilized by intermolecular N-H···and O-H···N hydrogen-bonding interactions. 2007 © The Japan Society for Analytical Chemistry.
