Abstract
In the 1:1 molecular adduct of 4,6-dimethylpyrimidine-2(1H)-thione and thiourea, C6H8N2S.CH4N2S, the pyrimidine ring is planar to within 0.0 37 (5) Angstrom and is protonated at the N atom rather than at the S a tom. It is linked to two other thiourea molecules by N ... H-N and S . .. H-N hydrogen bonds. Each thiourea molecule couples with two adjacen t thiourea molecules through hydrogen bonds, thereby forming a polymer ic chain extending along the c axis.
