Crystal and molecular structures of two triorganophosphinegold(I) 2-amino-cyclopent-1-ene-1-carbodithioates

The molecular structures of Ph₃PAu · (S₂CC₅H₆NH₂-2) and (4-MeOC₆H₄)₃PAu(S₂CC₅H₆NH₂-2) · CH₂Cl₂ display the expected linear S-Au-P coordination geometries. The hydrogen-bonding functionality in the 1,1-dithiolate ligands, i.e., —NH₂ groups, allows for the formation of hydrogen-bonded, i.e., N—H … S, mediated chains in the respective crystal structures.
