摘要

In a series of three chiral thioureas bearing a tetrahydronaphthyl fragment, none of the homochiral samples forms “true chiral” hydrogen-bonded motifs in the crystal. In all three cases, the addition of a second independent molecule to the cell is observed. In one case, a pseudosymmetric dimer was found in the crystal, and in the other two cases, a chain motif with alternation of independent molecules was found. The conformational transformations of the thiourea fragment are considered.
