Oxides hydrides

OrganometaUics and organometaHoids that yield peroxides in this manner include those in which Q is aluminum, antimony, arsenic, boron, cadmium, germanium, lead, phosphoms, siUcon, and tin and in which X is chlorine, bromine, alkoxy, acetoxy, cyano, oxide, hydride, hydroxyl, amino, alkyl, and boron tetrafluoride (28,33,44,60) (see Table 3). 

The corrosion behavior of plutonium metal has been summarized (60,61). a-Plutonium oxidizes very slowly in dry air, typically <10 mm/yr. The rate is accelerated by water vapor. Thus, a bright metal surface tarnishes rapidly in normal environments and a powdery surface soon forms. Eventually green PUO2 [12059-95-9] covers the surface. Plutonium is similar to uranium with respect to corrosion characteristics. The stabilization of 5-Pu confers substantial corrosion resistance to Pu in the same way that stabilization of y-U yields a more corrosion-resistant metal. The reaction of Pu metal with Hquid water produces both oxides and oxide-hydrides (62). The reaction with water vapor above 100°C also produces oxides and hydride (63). 

It is postulated that HOBO then reacts with BO to form gaseous boron oxide hydride, HBO, and boron dioxide, B02 (OBO).

The oxides, hydrides, halides, sulphides, sulphate , carbonates, nitrates, and phosphates are considered with the basic elements the other compounds are taken in connection with the aoidio element. The double or complex salts in connection with a given element include those associated with elements previously discussed. The carbides, silicides, titanides, phosphides, arsenides, etc., are considered in connection with carbon, silicon, titanium, etc. The intermetallic compounds of a given element include those associated with elements previously considered.

Malleable materials can be beaten into sheets. Ductile materials can be pulled into wires. Lustrous materials have a shine. Oxides, hydrides, and halides are compounds with 0, H, and halogens respectively. Measures of intermolecular attractions other than melting point are also higher for metal oxides, hydrides, and halides than for the nonmetal compounds. A dopant is a small quantity of an intentionally added impurity. The controlled movement of electrons in doped silicon semiconductors carries digital information in computer circuitry.

Primary hydride attack of the Mo center, intramolecular two-electron transfer from H via the Mo atom to the NO ligand, and protonation of the N atom with protons resulting from the (oxidized) hydride and solvent MeOH give the NH2O complex (Eq. 31). 

NaH decomposes at 210 °C and therefore above this temperature the reaction becomes equivalent to using hydrogen gas. To study deintercalation by hydride at higher temperatures the more thermally stable CaH2 has been used. Reaction of LaSrCo04 at 450 °C with CaH2 leads to the formation of an unusual transition metal oxide hydride, LaSrCoOsHoy. ... 

This compound was shown by neutron powder diffraction to adopt an unprecedented structure in which chains of C0O4 squares share comers to form chains that are linked to form a layer by H-bridges. The average cobalt oxidation state is 1.1+ and the C0O2 sheets in the starting material have been replaced with CoOHo,7 sheets in the oxide hydride product, which is consistent with a mechanism in which oxide vacancies created by oxide ion deintercalation are filled by intercalation of hydride ions.
