| description | 1,3-Diethyl-2-thiobarbituric acid reacts with 2-anisaldehyde to form the Michael addition product 2-anisylbis(1,3-diethyl-2-thiobarbitur-5-yl)methanate, which crystallizes as the title pyridinium salt, C5H6N+·C24H29N4O5S2−, when it reacts with the pyridine used to catalyse the reaction. There are two independent ion pairs in the crystal structure. The anion features a methine C atom connected to three six-membered rings; one of the rings carries a hydroxy group, which engages in hydrogen bonding with the carbonyl group belonging to another ring. The monoclinic unit cell emulates an orthorhombic unit cell, and is a twin with a minor twin component of 35%. |
