Crystal Structures of the Gold(I) Phosphinine Complexes [AuCl(C5H2P-2,6-Me2-4-Ph)] and [AuCl(C5H2P-2,4,6-Ph3)]

Abstract: The gold(I) phosphinine complexes [AuCl(C 5 H 2 P-2,6-Me 2 -4-Ph)] and [AuCl(C 5 H 2 P-2,4,6-Ph 3 )] were prepared and structurally characterised by single-crystal X-ray diffraction studies. In the former case, individual molecules are aggregated in the crystal as crossed dimers with an Au···Au distance of 3.60Å, compatible with a weak aurophilic interaction. In the latter case, intermolecular Au···π interactions involving the phosphinine ring are observed with Au···C distances in the range from ca. 3.32 to 3.… Show more

“…The Au−P distance (248 pm) is, however, appreciably longer than those found in linear gold(I) complexes of various substituted monodentate λ 3 ‐phosphinine ligands: ClAu(PC 5 H 2 t Bu 3 ‐2,4,6) (221.9(2) pm), ClAu(PC 5 H 2 Ph 2 ‐2,6‐Me−4) (av 220.62(7) pm), ClAu(PC 5 H 2 R 2 ‐2,6‐Ph‐4) (223.4(3) pm for R=Me; ca. 222 pm for R=Ph), ClAu(PC 5 H 2 R‐2‐Ph 2 ‐4,6) (av 220.8(1) pm; R=C 6 H 3 (OMe) 2 ‐3,4), ClAu{PC 5 HR‐2‐Me‐3‐Ph 2 ‐4,6} (220.40(7) pm; R=C 6 H 3 Me 2 ‐2,3), ClAu{PC 5 H 3 (SiMe 3 ) 2 ‐2,6} (221.1(2) pm), and [Au{PC 5 H 3 (SiMe 2 R) 2 ‐2,6} 2 ][GaCl 4 ] (av 228.2(4) pm for R=Me; av 226.3(2) pm for R=CCPh) . The most salient difference to the homologous py complex 4 is the relative disposition of the heteroaromatic EC 5 H 5 ring with respect to the metal coordination plane; the dihedral angle is much smaller for E=P (20.3°) than for E=N (81.2°).…”

“…Upon complexation, the π*-orbital strongly accepts electrons from transition metals so that the phosphinine metal complexes exhibit unique properties such as the acceleration of reductive elimination in catalytic cycles, biphilic reactivity, and strong photoluminescence resulting from MLCT. These properties have attracted great attention on the coordination chemistry of phosphinines . Among the metal–phosphinine complexes, group 11 metal complexes have been well-studied , since 1975 ,, as phosphinine ligands have high affinity with soft and electron-rich metal centers. Phosphinine group 11 metal complexes frequently exhibit μ 2 -coordination mode (Figure a), ,,, which endows the complexes with structural diversity. Among phosphinine group 11 complexes, there are only a few reports on the synthesis of phosphinine Ag­(I) complexes. ,, Therefore, structures and properties of phosphinine Ag­(I) complexes are still elusive.…”
