The mu2-silylene-bridged iron complexes [Cp(OC)(2)Fe](2)SiX(2) (X = F (2), Br (4), I (5)) have been prepared from the mu2-SiH(2) functional precursor [Cp(OC)(2)Fe](2)SiH(2) (1) by hydrogen/halogen exchange, using HBF(4), CBr(4), and CH(2)I(2), respec

The (2-Py)2N ligand shows much more conformational freedom than the (2-Py)2P anion in aluminium coordination. The two isomers [Al{(NPy)Py}3] (1a) and [Al{(NPy)Py}2(Py2N)] (1b) were isolated, the former containing exclusively cistrans ligands, and the

Density functional theory (DFT) calculations were carried out for trans-[RhX(L)(PMe3)2] (L=CCH2, CCHC6H5, CO, 2,6-Me2C6H3NC, C2H4) which served as model compounds for the analysis of the vibrational spectra of related complexes. The characteriz

The surface enhanced Raman spectroscopy (SERS) spectrum of caffeine is recorded on a silver colloid at different pH values. It is discussed on the basis of the SERS "surface selection rules" in order to characterize its vibrational behavior on such a

The reaction of [RhCl(C8H14)2]2 with 4 equiv. of PiPr3 and an equimolar amount of 1,3-C6H4(NC)2 in benzene–ether led to the formation of the dinuclear diisonitrile complex trans-[{RhCl(PiPr3)2}2{μ-1,3-(CN)2C6H4}] (2) in 75% yield. The related iodo

The theoretical reaction pathways of the irradiation of Cp(CO) 2 FeSiH 2 CH 3 and Cp(CO) 2 FeCH 2 SiH 3 have been studied by means of DFT calculations using the BPW91/6-311G* method. Although the calculated characteristic vibrational modes of the met

Reaction of PPN[W(CO)3(dmpe)(SH)] 2 (PPN = Ph3PNPPh3, dmpe = Me2PC2H4PMe2) with aqueous formaldehyde in the presence of trifluoroacetic acid gives the thioformaldehyde complex mer-[W(CO)3(Me2PC2H4PMe2)(η2-SCH2)] 3 in almost quantitative yield. The i
