Cluster synthesis by photolysis of R3PAuN3. Crystal structure of OH and NO3
Beuter, Georg,Straehle, Joachim
, p. 67 - 78 (1989)
Photolysis of R3PAuN3 (1) results in a reductive elimination of the azide group yielding R3PAu0 moieties which then combine to form Au clusters.In the presence of metal carbonyls heterometalic clusters are obtained.In the case of Mo(CO)6 the ca
Some Au3Ru3 clusters. X-ray structures of Ru3(μ3-CMeCHCMe) (CO)8{Au3(PPh3)3} and Ru3(μ3-C2Ph) (CO) 8{Au3(PPh3) 3}

Several clusters containing Au3Ru3 cores have been made from reactions between hydrido-triruthenium clusters or AuRu3 clusters and [O{Au(PPh3)}3][BF4]. In the former case, the Au3(PPh3)3 group acts as a three-electron donor, replacing (H + CO). The molecular structures of Ru3(μ3-CMeCHCMe(CO)8{Au3(PPh3)3} (4) and Ru3(μ3-C2Ph(CO)8{Au3(PPh3)3} (13) have been determined by X-ray crystallography. Comparisons are made between the parent Ru3 clusters and their aurated derivatives, which may contain open (bent) or closed triangular Au3P3 moieties, according to whether there is more or less electron density on the cluster.
LXVII. Reactions of some Fe-Ir clusters. Crystal structures of Fe2Ir(μ-H)(μ3-CCHPh)(CO)8(PPh3) and Au2Fe2Ir(μ4-C2Ph)(CO)7(PPh3)3

Isomeric hydrido-vinylidene and -alkyne complexes Fe2Ir(μ-H)(μ3-X)(CO)8(PPh3) (X = CCHPh, H2CPh) were obtained from Fe2Ir(μ3-C2Ph)(CO)8(PPh3) and H2 or H-/H+.The X-ray structure of the vinylidene complex is repo
A novel method of introducing the Au2(PR3 ) 2 (R = Ph, OMe) unit into metal clusters X-ray structures of three complexes containing Au2Ru3 cores and of Ru6C(μ-CO) 2(CO) 14{Au(PPh3)}2

The complexes Ru3(μ3-C6H3R){μ-P(C6H4R-3)2}2(CO)6{Au2(PPh3)2} (R = H (2), Me), Ru3(μ3-PPhCH2PPh(C6H4-2)}(CO)8-{Au2(PR3)2} (R = Ph, OMe (5)), Ru3(μ3-NPh)n(CO)10-n{Au2(PPh3)2} (n = 1 (6), 2) and Ru3(μ3-S)2(CO)8{Au2(PPh3)2} have been obtained from reactions between [O{Au(PR3)}3]+ (R = Ph, OMe) and the 'parent' Ru3 clusters; X-ray structural studies of 2, 5 and 6 show that a CO group has been replaced by an Au2(PR3)2 fragment. In contrast, the two Au(PPh3) groups bridge opposite Ru-Ru bonds in Ru6C(μ-CO)2(CO)14{Au(PPh3)}2 (9; X-ray structure). The known complexes Os3(CO)11{Au2(PPh3)2}, and Os3H2-n(CO)10-{Au(PPh3)}n (n = 1, 2) were obtained from Os3(CO)12 and Os3H2(CO)10 respectively.

The specific additions of one, three or four Ph3PAu groups to - (M = Mn, Re) are described.Thus - in THF reacts with BF4 to give BF4.An X-ray crystal structure of the M = Mn example shows the cation to have a trigonal bipyramidal Au4Mn core with the Mn in an equatorial site.The previously known neutral (Ph3PAu)3M(CO)4 clusters are formed by addition of two Ph3PAu groups, using the mixed reagent BF4/, to Ph3PAuM(CO)5, which itself is readily prepared from - and Ph3PAuCl.
Cluster chemistry. 62. Preparation of the heptanuclear clusters Ru5M2(μ5-C2PPh2)(μ-PPh2)(CO)12 (PPh3)2 (M = Ag, Au). X-ray structure of Au2Ru5(μ5-C2PPh2)(μ-PPh2) (PPh3)2{P(OEt)3}

The heptanuclear title complex was obtained from reactions between Ru5(μ5-C2PPh2)(μ-PPh2)(CO)13 and a mixture of [O{Au(PPh3)}3][BF4] and [ppn][M(CO)n] (M = Co, n = 4; M = Mn, n = 5) or by reduction (Na/Hg or K[HBBu38]) or the Ru5 complex and treatment with AuCl(PPh3); the silver analogue was made by the latter route. The structure of a P(OEt)3 derivative of the Au2Ru5 cluster was determined. The metal core consists of an Ru/AuRu2/Au trigonal bipyramid, two edges of which are bridged by Ru atoms. Addition of the Au2(PPh3)2 unit has resulted in cleavage of one of the Ru-Ru bonds present in the original Ru5 cluster. Au2Ru5(μ5-C2PPh2)(μ-PPh2)(CO)11 (PPh3)2{P(OEt)3} is triclinic, space group P1?, with a = 14.031 (15) A, b = 16.741 (4) A, c = 18.721 (6) A, α = 98.64 (2)°, β = 97.61 (6)°, γ = 98.04 (6)°, and Z = 4; 6848 data were refined to R = 0.0595 and Rw = 0.0617.
