Two organometallic compounds containing zinc and manganese in different ratios are used as single-source precursors for the preparation of various new, bimetallic oxide materials with nanoscaled dimensions. It is shown that the materials synthesis can be performed in the solid-state, the liquid-phase, and even in the gas-phase. The molecular composition of the precursors determines the composit...

New metal-free phthalocyanines (8–9) fused in peripheral positions with four tetraazadithiahexaoxa supercryptands were synthesized by tricyclotetramerization of isoindolinediimine derivatives of supercryptands (6–7). Metallophthalocyanines (10–11) were prepared by the reaction of the metal-free phthalocyanines with metal salts or cyclotetramerization of dicyano compounds (4–5) and anhydrous sal...

Two compounds with quadruply bonded Mo2(4+) species having isonicotinate ligands bound through the carboxylate group have been designed to act as anglers by luring metal-containing Lewis acids to bind to the N-pyridyl group. The corner pieces are Mo2(DAniF)3(O2CC5H4N) and cis-Mo2(DAniF)2(O2CC5H4N)2, DAniF=N,N'-di(p-anisyl)formamidinate. The heterometallic molecular rods -Ni(acac)2-and-Rh2(O2CCH...

Ultrafast electronic relaxation measurements in thiol-capped Au11 reveal an excited state lifetime of >500 ps, similar to Au13 and Au28. Upon extended exposure to laser light, a small amplitude, fast relaxation component was observed and attributed to formation of larger particles or aggregates. The long lifetime, combined with a lack of excitation intensity dependence, indicates that Au11 beha...

Fine aerosol particles were collected separately during daytime and nighttime at a tropical pasture site in Rondônia, Brazil, during the burning and dry-to-wet transition period in 2002. Total carbon (TC) and water-soluble organic carbon (WSOC) were measured by evolved gas analysis (EGA). Based on the thermochemical properties of the fine aerosol, the relative amounts of the volatile and refrac...

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 ...

Solid-state metal hydrides provide a safe and efficient way of storing hydrogen (Schlapbach 2002). They are commercialized for use in rechargeable batteries and developed for energy conversion devices such as fuel cells (see Hydrogen Metal Systems: Electrochemical Reactions). A great majority of metal hydrides derives from intermetallic compounds and alloys (see Hydrogen Metal Systems: Hydride ...
