Cruciaromaticity in organometallic compounds

A recent suggestion, that transition metal complexes of unsaturated ligands can be regarded as cruciconjugated, is explored by studies of various complexes of Fe(II), the aromaticity of the resulting i systems being analyzed in terms of PMO theory. This approach is also applied to porphyrin. The conclusions are supported by preliminary SCF and MNDO calculations.

One-Electron Oxidation of Heterodinuclear Organometallic Compounds Having

The electrochemical behavior of several heterometallic compounds having polyphosphido bridges has been investigated. Reversible one-electron oxidations were observed for Cp*Fe(P5)TaCp′′ (2), Cp*Fe(P5)[Ir2(CO)2Cp*2] (3), and Cp′′′2Co2(P2)2 (4) (Cp* ) C5M5, Cp′′ ) C5H3Bu2, Cp′′′ ) C5H2Bu3). In contrast to the pseudo-sandwich polyphosphido complex Cp*FeP5 (1), compounds 2-4 undergo very facile oxi...

Clustering in Nanostructured Carbon: Evidence of Electron Delocalization

The electronic properties of disordered carbon based materials can be discussed in terms of the clustering of the sp 2 carbon phase and delocalization of the electron wavefunction. In smooth amorphous carbon thin films this results in a mixed phase material of conductive sp 2 clusters embedded in an electrically insulating sp 3 matrix. The delocalization of the electron wavefunction associated ...

Therapeutic Organometallic Compounds

Most drugs used today are purely organic compounds. Especially after the enormous success of the cisplatin (Fig 1) in tumor treatment, interest in metal complexes has grown (Allardyce & Dyson, 2006). Synthetic organometallic compounds are generally considered to be toxic or non-compatible with biological systems. Despite this perception, the medicinal properties of organometallic compounds, in ...
