ResumoReaction of arenethiolate anions with [Ag(PPh3)4] yields novel silver(1) thiolate phosphine complexes, which are very soluble in common solvents. The crystal structure of [{Ag(SPh)(PPh3)}4] has been solved: C90H80Ag4P4S4, triclinic, space group P1. a = 12.263(2) b = 13.124(2), c = 15.063(2)Å, α=69.596(9), β = 81.074(11), γ=68.944(12)°, U = 2119.2(6)Å3, Z = 1. The complex has a highly-distorted chair structure in the solid state, with short silver-silver contacts of 3.1300(3)Å. [{Ag(SPh)(PPh3)}4] is a rare example of a complex containing only non-chelating ligands showing indications of solid-state silver(1)-silver(1) interactions.
