The geometric structures of small cationic rhodium clusters Rh(n)(+) (n = 6-12) are investigated by comparison of experimental far-infrared multiple photon dissociation spectra with spectra calculated using density functional theory. The clusters are found to favor structures based on octahedral and tetrahedral motifs for most of the sizes considered, in contrast to previous theoretical predict...

a new method for analysis of trace amount of rh(iii) ions by magnetic activated carbon modified with 2,3,5,6-tetra(2-pyridyl)pyrazine (mac/tppz) as the magnetic sorbent has been proposed. the proposed adsorbent was found to be advantageous over conventional solid phase extraction (spe) in terms of operational simplicity and low time-consuming. the experimental parameters affecting the extractio...

The Rhodium tris carboxylate of the type, RhL3 was prepared by the reaction of Rhodium trichloride with sodium salt of furoic acid in 1:3 stoichiometry. The complexes obtained were characterized by elemental analysis, IR and 1H, 13C NMR spectroscopic techniques. Based on spectroscopic data ligand coordination through oxygen atoms of the carboxylate group has been suggested. The metal complex ha...

Sulfoxides are uncommon substrates for transition-metal catalysis due to their propensity to inhibit catalyst turnover. In a collaborative effort with Ken Houk, we developed the first dynamic kinetic resolution (DKR) of allylic sulfoxides using asymmetric rhodium-catalyzed hydrogenation. A detailed mechanistic analysis of this transformation using both experimental and theoretical methods revea...

The germanide Ce2Rh3Ge5 was synthesized from the elements in a bismuth flux, and the structure was refined from single-crystal X-ray diffractometer data: U2Co3Si5 type, Ibam, a = 1010.1(2), b = 1210.4(2), c = 599.1(1) pm, wR = 0.0596, 760 structure factors, 31 variables. The rhodium and germanium atoms build up a three-dimensional [Rh3Ge5] network (242 – 269 pm Rh–Ge; 300 pm Rh–Rh; 266 pm Ge–Ge...

In noble metals, surface plasmons may be induced by incident light, resulting in good plasmonic properties that can widely utilized. this work, an optical nanomaterial based on a spherical nanoshell structure consisting of rhodium and dielectric is proposed. The scattering efficiency electric field are calculated via the finite difference time domain method, respectively varying nanoparticle ra...

A first work on rhodium-catalyzed para -selective C–H alkynylation has been reported and its mechanistic insights were gleaned from experimental computational studies.
