Methyl(triphenylphosphine)gold

Early–Late Heterometallic Complexes of Gold and Zirconium: Photoluminescence and Reactivity

“…As one methyl group is disordered, only the structural parameters of Au1−C1 are discussed. The Au−C1 distance of 2.057(13) Å (Au−C1) is considerably shorter than the corresponding bond length in [AuMe(PPh 3 )], and more similar in length to Au−C bonds in Au NHC complexes . Again, a near linear arrangement of the heavy atoms is seen (Au1‐Zr1‐Au2=169.54(5)°).…”

Alkylgold complexes by the intramolecular aminoauration of unactivated alkenes

“…The phosphine–gold bond length of 2.29 Å is typical for a phosphine gold(I) complex. 18a The C19–Au bond length (2.07 Å) is comparable to that of MeAuPPh 3 (2.12 Å). 18b The N–C–C–Au dihedral angle is an almost perfect antiperiplanar arrangement.…”

“…18a The C19–Au bond length (2.07 Å) is comparable to that of MeAuPPh 3 (2.12 Å). 18b The N–C–C–Au dihedral angle is an almost perfect antiperiplanar arrangement. The crystal structure of piperidine alkylgold complex, 20 , displayed similar characteristics with a C–Au–P angle of 177° and bond lengths of 2.08 and 2.28 Å for the C–Au and Au–P bonds, respectively (Fig.…”

Linear GoId(I) Derivatives with Bulky Phosphine and Imidazolato Ligands. X-Ray Crystal Structure of 1-(C6H11)3PAu-2-i-Pr-Imidazole · C6H6

“…The A u -P distance (2.255(2) Ä) is only slightly longer than those reported for the following compounds: Ph3PAuCl, 2.235(3) [19], [Ph3PAu(3,5-dimethylpyrazole-./V]+, 2.235(5) [20], C lA uP(Ph2)C H 2(Ph2)P A uC l, 2.238(5) [21] and [(Ph3PA u)2Cl]+, 2.230(5), 2.239(4), 2.240(6) and 2.232(4) Ä [22]. The frans-influence of an im idazolato anion seems then to be com parable with that of a neutral pyrazole or with that of a chloride ion, and it is clearly lower than that of an organic group, a phosphine or a cyanide ion, for which the following A u -P distances are available: Ph3PA uC H 3, 2.279(8) [23] [(Ph3P)2A u]+, 2.323(4) a n d 2.339(4) [17], Ph3PA uCN, 2.27(1) [25] and [(Cy3P)2Au] + , 2.29(11) or 2.316(13) [15].…”
