Bis(N,N'-dimethylthiourea-S)gold(I) Perchlorate and Bis(N,N'-diethylthiourea-S)gold(I) Perchlorate

The gold(I) center in each of the title complexes, [Au(C₃H₈N₂S)₂]ClO₄, (1), and [Au(C₅H₁₂N₂S)₂]ClO₄, (2), is essentially linearly coordinated through the S atoms of the dialkylthiourea ligands. The complexes crystallize in pairs, with an Au...Au separation of 3.620 (4) and 4.294 (2) Å for (1) and (2), respectively. The perchlorate anion does not interact with the bis(alkylthiourea)gold(I) cation. Compound (1) sits on a twofold axis.
