An Octanuclear Gold(I) Cube with Amidinate Ligands Containing Two Hyper-coordinate Ylide Carbon Atoms
نویسندگان
چکیده
Disparate properties of gold(I) converge to produce the first known cube assembly of eight Au(I) atoms connected by four N-bridging amidinate ligands on the sides of the cube, capped above and below by hyper-coordinate carbon atoms from a phosphorous ylide. There are no phosphines coordinated to the Au(I) atoms. The cluster is formulated as [Au8{CH(NC8H9)2}4{(ηC)P(C6H5)2(CH3)}2]. It displays a strong green luminescence under UV light. The novel product was generated in an attempt to produce luminescent species of gold(I) with mixed Cand Ncoordination, an arrangement not abundant in the literature. The formation and structure of this cluster is reported.

Zwitterionic amidinates as effective ligands for platinum nanoparticle hydrogenation catalysts.
Ligand control of metal nanoparticles (MNPs) is rapidly gaining importance as ligands can stabilize the MNPs and regulate their catalytic properties. Herein we report the first example of Pt NPs ligated by imidazolium-amidinate ligands that bind strongly through the amidinate anion to the platinum surface atoms. The binding was established by 15N NMR spectroscopy, a precedent for nitrogen ligan...
متن کاملAn octanuclear coordination cage with a 'cuneane' core--a topological isomer of a cubic cage.
The octanuclear coordination cage [Ni(8)(L(14Naph))(12)](BF(4))(16) has the core structure of a 'cuneane'--a toplogical isomer of a cube--with a metal ion at each of the eight vertices and bridging ligand spanning each of the twelve edges; this is the only possible 8-vertex polyhedron other than a cube that will form a cage in which each metal is connected to three others.

Rhodium(I) complexes of the hybrid ylide-phosphine ligands, Ph2P(CH2)nPPh2(CHC(O)C6H5) (n = 1: dppm-yl, or 2: dppe-yl) have been synthesised from [Rh(μ-Cl)(COD)]2 (COD = 1,5-cyclooctadiene) and characterized by NMR spectroscopic and X-ray structural methods. The dppe-yl behaves as an ambidentate ligand; it functions as a monodentate P-donor ligand with a dangling ylidic carbon in the neutral ch...
متن کاملLow coordinate lanthanide(II) complexes supported by bulky guanidinato and amidinato ligands.
The preparation of a series of homoleptic, four-coordinate lanthanide(ii) complexes, [Ln(Priso)(2)] (Ln = Sm, Eu or Yb) incorporating the bulky guanidinate ligand Priso(-) ([(ArN)(2)CNPr(i)(2)](-), Ar = 2,6-diisopropylphenyl) is described. X-ray crystallography shows the complexes to be isostructural and to exhibit coordination geometries midway between tetrahedral and planar. Comparisons betwe...
متن کاملRemarkably short metal-metal bonds: a lantern-type quintuply bonded dichromium(I) complex.
The field of quadruply bonded dinuclear complexes in which two metal atoms are embraced by eight ligands has been considered mature. The bonding and electronic structures of these compounds have been well understood, ever since the discovery of the first dimetal species containing a quadruple bond, [Re2Cl8] 2 , over 40 years ago. The quest for thermally stable and isolable dinuclear complexes w...
