Title: Electron states in metal clusters

Abstract

Radiative transitions in metal clusters are analyzed in terms of quantum transitions of valence electrons that interact with surrounding valence electrons and ion cores. The analysis is based on the solution of the Thomas-Fermi equation for valence electrons in a spherical cluster. The quantum states of valence electrons and the energy and the dipole moments of transitions are determined in the quasiclassical approximation. It is shown that the frequencies of dipole oscillations and the dipole moments of the transitions strongly depend on the size of a cluster.

  • Of the transition metals, osmium forms the most neutral binary carbonyls. The crystal structures of Os/sub 3/(CO)/sub 12/, Os/sub 5/(CO)/sub 16/, Os/sub 5/(CO)/sub 19/, Os/sub 6/(CO)/sub 18/, Os/sub 7/(CO)/sub 21/, and Os/sub 8/(CO)/sub 23/ have been determined. Pentacarbonylosmium, Os(CO)/sub 5/, and nonacarbonyldiosmium, Os/sub 2/(CO)/sub 9/, are also known as is Os/sub 6/(CO)/sub 21/, previously considered to be Os/sub 6/(CO)/sub 20/. However, to their knowledge there are no previous reports of a tetranuclear binary carbonyl of osmium. Given the stability of Os/sub 3/(CO)/sub 12/ and allowing for the increase in nonbonded interactions, one might expect that Os/sub 4/(CO)/sub 16/ with amore » square arrangement of metal atoms would be stable. Here they report the synthesis and structure of Os/sub 4/(CO)/sub 15/ the first tetranuclear binary carbonyl of osmium, along with the synthesis and structure of (eta/sup 5/-C/sub 5/Me/sub 5/)(OC)IrOs/sub 3/(CO)/sub 11/. These clusters have unusual planar skeletons with adjacent short and long metal-metal bonds.« less
  • Addition of primary alcohols, RCH{sub 2}OH (> 6 equiv), to hydrocarbon solutions of M{sub 2}(O-t-Bu){sub 6} compounds has led to the isolation of the first homoleptic series of cluster alkoxides M{sub 4}(OCH{sub 2}R){sub 12} for both M = Mo and W where R = i-Pr, Cy (Cy = cyclohexyl), Cp (Cp = cyclopentyl), and c-Bu (c-Bu = cyclobutyl). The NMR data ({sup 1}H and {sup 13}C) indicate a common structural unit for this class of compounds containing a molecular mirror plane. For each M{sub 4}(OCH{sub 2}R){sub 12} compound there are eight types of alkoxide ligands in the integral intensity 2:2:2:2:1:1:1:1.more » Those having integral intensity two possess diastereotopic methylene protons, indicating that they do not lie on the mirror plane, whereas the other four alkoxides (1:1:1:1) are contained within the mirror plane. Though these compounds yield crystals from 1,2-dimethoxyethane, they failed to diffract beyond 10{degree} indicating a molecular disorder within hexagonal packing of M{sub 4} units. However, the cyclobutylmethoxide derivatives crystallize with an additional molecule of alcohol, M{sub 4}(CH{sub 2}-c-Bu){sub 12}(HOCH{sub 2}-c-Bu), and the molecular structure of the molybdenum compound was determined by an X-ray study. Crystal data for Mo{sub 4}(OCH{sub 2}-c-Bu){sub 12}(HOCH{sub 2}-c-Bu) at {minus}156{degree}C: a = b = 19.952 (7) {angstrom}, c = 34.755 (16) {angstrom}, Z = 8, d{sub calcd} = 1.43 g cm{sup {minus}3}, and space group Pr{sub 1}. The unit cell contains two crystallographically independent molecules that are essentially equivalent with respect to M-M and M-O distances and angles. In each there is a central Mo{sub 4} butterfly with a dihedral angle between the Mo{sub 3} triangles of 132.5{degree}.« less
  • A knowledge of the properties of small metal particles is essential to the understanding of catalysis on a molecular level. In this regard, one particularly important property is the rate at which the dissociation energy of a small metal cluster approaches the bulk cohesive energy. The present research concerns the effect of electron correlation on the dissociation energy of a particularly stable beryllium cluster, the tetrahedral Be/sub 4/ system. A contracted Gaussian basis set of size Be(9s 4p/5s 2p) was adopted in conjunction with the recently developed theory of self-consistent electron pairs (SCEP). Several new theoretical and computational wrinkles aremore » discussed, including the incorporation of the SCEP/coupled electron pair approximation (SCEP/CEPA). The Be/sub 4/ results provide strong evidence for the reliability of the Hartree--Fock approximation for alkaline earth cohesive energies. As suggested earlier the Be/sub 4/ dissociation energy appears to be approx.40 kcal/mole. Analogous studies of the Be/sub 2/ molecule are reported. (AIP)« less
  • Hueckel model with one [ital s]-electron per atom is used to study the geometries and electronic structures of clusters of 9 to 22 atoms. Two different optimization schemes for obtaining the ground states are used; (i) minimization of an approximate Hueckel ground state energy starting from a random geometry and (ii) simulated annealing. Both methods give similar and new ground state geometries for clusters with 10 to 14 atoms. All clusters with more than 10 atoms will be distorted if the bond distance is allowed to vary [plus minus]5.5%. The ground states of clusters with atoms 10, 11, 12, andmore » 14 are found to have the [ital N]=9 cluster as the basic building block, whereas the [ital N]=13 cluster is a distorted cuboctahedron. As a general trend, the deformation of clusters increases from atom number 8 to 14 and shrinks again from 15 to 20 atoms, in accordance with jellium model results.« less
  • The existence of image states in small clusters is shown, using a quantum-mechanical many-body approach. We present image state energies and wave functions for spherical jellium clusters up to 186 atoms, calculated in the GW approximation, where G is the Green's function and W is the dynamically screened Coulomb interaction, which by construction contains the dynamic long-range correlation effects that give rise to image effects. In addition, we find that image states are also subject to quantum confinement. To extrapolate our investigations to clusters in the mesoscopic size range, we propose a semiclassical model potential, which we test against ourmore » full GW results.« less
