A novel cysteine-incorporated anthraquinone derivative was synthesized, and its molecular structure was determined by X-ray crystal analysis. Each mercapto group was located separately and did not form a disulfide bond, and hydrogen bondings and π-π interaction were observed from the packing structure.
Keywords: X-ray crystal analysis; anthraquinone; artificial molecules; cysteine; mercapto group; packing structure; π-π interaction.
