The Reactivity of HRu3(CO)9C2BUt. The Synthesis and crystal structure of (PPH3)AuRu3(CO)9C2BUt, a new ruthenium-gold cluster

Cluster-containing carbon-rich molecules: Reactions of ruthenium cluster carbonyls with {Au(PR3)}2(μ-CCCC) (R=Ph, tol)

“…The ranges of atom separations of each type exceed the e.s.d.s but nevertheless fall within the values previously found for complexes of this type [15][16][17][18][19][20]. Thus, the Au-Ru distances fall in the range 2.7465(3)-2.7977(5) Å , with Au-P separations of between 2.2842(9) and 2.2974(7) Å .…”

“…Considering the two carbon atoms, their bonding is closely related to that of an alkynyl group, such as those found in M 3 (l-H)(l 3 ,g 2 -C 2 R)(CO) 9 (M = Fe, Ru, Os), of which several examples have been structurally characterised [13]. The well-known isolobal relationship between H and Au(PR 3 ) [14] led to the isolation and characterisation of several related gold-containing Ru 3 and Os 3 clusters, the first example being AuRu 3 (l 3 ,g 2 -C 2 Bu t )(CO) 9 -(PPh 3 ) [15] obtained from Ru 3 (l-H)(l 3 ,g 2 -C 2 Bu t )(CO) 9 by deprotonation with NaH or K-Selectride [16], followed by reaction of the resulting monoanion with AuCl(PPh 3 ). The same complex was also described by Salter [17].…”

Gold–Heterometal Interactions and Bonds

“…Similar (AuM 2 )M cores were found for the Au-Ru [261][262][263][264][265][266][267][268][269][270][271][272][273][274][275][276][277][278] and Au-Os [276,[279][280][281][282][283][284][285][286][287][288][289][290] [290]. Bis-cluster species in which two (AuRu 2 )Ru cores are connected through buta-1,3-diyne derivatives as bridging ligands have been described [290].…”

Synthesis of ferrocenylacetylide derivatives of gold-ruthenium and gold-osmium clusters. Crystal structures of M3(AuPPh3)(C≡CFc)(CO)9 (M=Ru or Os; Fc is ferrocenyl)

“…148.57(4) 148.1(1) P(I)--Au(I )~M (2) 149.80(4) 149.9(I) CII I)--C{ 10)--Mq3) 153.2 (5) 153(I) C( IO)--C( I I)--C(t2) 145. t (6) 144(t) H(4) atoms in the substituted cyclopentadienyl ring of the ferrocenyl group because these protons are manifested as two signals in the I H N M R spectrum. Thermal reactions of clusters 3a and 3b with Ru3(CO)t_, were performed (see Scheme 2).…”
