1-(4-Chloro-phen-yl)-4,4,6-trimethyl-3,4-dihydro-pyrimidine-2(1H)-thione.

ABSTRACT: The dihydro-pyrimidine ring of the title compound, C(13)H(15)ClN(2)S, adopts an envelope conformation with five almost coplanar atoms (r.m.s. deviation = 0.054?Å) and the C atom bearing the two methyl substituents deviating from this plane by 0.441?(2)?Å. The best plane through the five almost coplanar atoms forms a dihedral angle of 89.56?(5)° with the benzene ring. The crystal packing is characterized by centrosymmetric dimers connected by pairs of N-H?S hydrogen bonds.

Neighbouring mol-ecules are linked together by inter-molecular N-H?N hydrogen bonds into a one-dimensional infinite chain along the [101] direction and short Cl?Cl contacts link the chains into a three-dimensional network. There is also a significant ?-stacking inter-action between the planar sections of the six- and five-membered rings.
