Abstract

EXAFS spectroscopy of solid samples suggests that Au(dien)Cl/sub 3/ is a molecular entity with pseudooctahedral coordination. The three nitrogen donors from the dien ligand and one chlorine form an equatorial plane with two axial Au-Cl bonds of uncertain length (2.6 or 3.0 A) completing the coordination sphere. A single-crystal X-ray diffraction study confirms the overall structure but yields axial Au-Cl lengths of 3.121 (4) and 3.183 (3) A. The crystals are orthorhombic, space group Pbca, with cell constants a = 12.442 (5), b = 12.878 (9), and c = 13.177 (3) A and eight molecules per unit cell. These molecules were further characterized by Raman spectroscopy in solution as well as the solid state. Equatorial and axial Au-Cl stretching vibrations are observed for both phases, indicating some stability of the Au-Cl(axial) bonds in solution. 25 references, 3 figures, 4 tables.
