The core of the compound is thiourea, with each nitrogen connected to two methyl groups. The molecule is planar. The C=S bond is 0.02 Å shorter than in thiourea itself.[1]
Sulfur is the basic site in tetramethylthiourea. Alkylation occurs at S, affording isothiouronium salts.[2]
Tetramethylthiourea forms many coordination complexes. Two examples tetrahedral CoCl2L2 and linear AuBrL, where L = ((CH3)2N)2C=S.[3][4]
