The title compounds were synthesized and characterized by IR, 1H-NMR, Mass and elementary analysis and single-crystal X-ray diffraction. In 1a, intermolecular C-H…π interactions produce a three-dimensional network. In 1b, intermolecular C-H…O hydrogen bonds generate an R22(22) ring. The hydrogen bonding is supported by C-H…π interactions.
