Abstract

Tetrakis(diphenylphosphanylm ethyl)methane C(CH2–PPh2)4 was prepared (following modified literature methods), its structure determ ined by X-ray diffraction methods, and its spectroscopic data complemented. The tetranuclear gold(I) com plex C[CH2–PPh2·AuC1]4 was obtained by treatm ent of the tetrafunctional ligand with four equivalents of (Me2S)AuCl, and its structure was also determined. The changes in structure and conformation as compared to that of the free ligand provide evidence for attractive intramolecular Au…Au interactions for one pair of gold(I) centers. Owing to steric congestion of the molecule, the remainder pair are independent structural units not engaged in metal–metal interactions.
