ResumoCadmium(II) chloride reacts with toluene-3,4-dithiol (H 2 TDT) to give Cd (TDT), which is apparently a homopolymer in the solid state. Adducts with neutral monodentate and bidentate donors have been prepared. The structure of the salt (Ph 4 As) 2 [Cd(TDT) 2 ] was determined by X-ray crystallography. Crystals of this compound are monoclinic (P2 1 /c), with a = 23.032 (4) Å, b = 12.396(4) Å, c = 22.529(5) Å, β = 111.106(2)°. The structure was refined by least-squares methods to a final R-valueof 0.0469 for 2523 "observed" reflections. The anion is a distorted tetrahedral, mononuclear species with Cd—S bond distances ranging from 2.488(5) Å to 2.531(4) Å. This anion is also a Lewis acid, forming complexes of the type [Cd(TDT) 2 L] 2− with neutral bidentate ligands.
