Clusteraufbau durch Photolyse von R3PAuN3. VIII. Synthese und Kristallstruktur von [(Ph3PAu)5Mo(CO)4]PF6 · CH2Cl2 und (Ph3PAu)3Co(CO)3

Abstract: Die Photolyse einer Mischung von Ph3PAuN3 und Mo(CO)6 in THF ergibt den Cluster [(Ph3PAu)5Mo(CO)4]+ (l), der nach Zugabe von PF6− aus CH2Cl2/Diisopropylether als oranges 1 · PF6 · CH2Cl2 mit der Raumgruppe P21/c und a = 1681,4(5), b = 2215,6(12), c = 2761,5(9) pm, β = 91,54(3)°, Z = 4 kristallisiert. Das Au5Mo—Gerüst von 1 bildet eine einfach überkappte trigonale Bipyramide mit dem Mo—Atom in äquatorialer Position und nahezu gleich langen MoAu‐Abständen von 279,9(5) bis 284,6(7) pm zu allen fünf Au‐Atomen.

“…Investigations by Mössbauer spectroscopy indicated stronger Au−Au interactions in the latter than in its FeAu 2 precursor, which was associated with a tetrahedral structure of the metal core. Precedents for tetrahedral [m]{Au(PPh 3 )} 3 clusters include those where [m] = V(CO) 5 and Co(CO) 3 , whereas when [m] = Mn(CO) 4 a planar arrangement of the metal atoms was found
4 Radial disbribution functions for [{η 5 -(1-phenylborole)}Fe(CO) 2 {Au(PPh 3 )} 3 ]PF 6 ( 4 ) obtained from the experimental data (◇ data points) and calculated for a tetrahedral model of the cation (continuous line).
