Metals Cross Reference Table

This Chapter is arranged in the sane fornat used in Volune 13, and consists of a conprehensive list of organonetallic conpounds whose structures have been detemined by X-ray i neutron or electron diffraction methods and reported during 1984. The definition of metals remains the same, and the ordering of formulae in the Main Table is based on the modified Hill system as before. Under the Structure heading the line formula is an attempt to describe the structural identity of the compound. The less familiar abbreviations used are listed at the end of the Main Table. Nixed metal compounds appear only once in the Main Table. The Metals Cross Reference Table can be used to locate mixed metal compounds in the Main Table which appear alphabetically under another metal. 

I, 2, and S of this series. The tabulation is intended to be comprehensive and in order to make the structural information more accessible a set of cross reference tables, based upon metal and ligand type, is included (Section 3). Section 4 contains a table of metal - metal bond distances and notes on selected molecular structures are presented in Section 5. 

In this section, we consider physical properties of the J-block metals (see cross references in Section 19.1 for further details) an extended discussion of properties of the heavier metals is given in Section 22.1. Nearly all the J-block metals are hard, ductile and malleable, with high electrical and thermal conductivities. With the exceptions of Mn, Zn, Cd and Hg, at room temperature, the metals possess one of the typical metal structures (see Table 5.2). The metallic radii (rjnetai) for 12-coordination Table 5.2 and Figure 19.1) are much smaller that those of the -block metals of comparable atomic number Figure 19.1 also illustrates that values of /-metal ... 

Polymer-based rocket propellants are generally referred to as composite propellants, and often identified by the elastomer used, eg, urethane propellants or carboxy- (CTPB) or hydroxy- (HTPB) terrninated polybutadiene propellants. The cross-linked polymers act as a viscoelastic matrix to provide mechanical strength, and as a fuel to react with the oxidizers present. Ammonium perchlorate and ammonium nitrate are the most common oxidizers used nitramines such as HMX or RDX may be added to react with the fuels and increase the impulse produced. Many other substances may be added including metallic fuels, plasticizers, stabilizers, catalysts, ballistic modifiers, and bonding agents. Typical components are Hsted in Table 1. 

The combination of different fluorescent metal indicators with inert luminescent reference beads consisting of poly(acrylonitrile) containing Ru(dpp)3 leads to a sensor array in a microwell plate format, suited for ratiomet-ric time-resolved imaging [95]. The data can be acquired with the help of the f-DLR method (for details see Sect. 2.3). A cross-reactive sensor array was arranged for the determination of mixtures of calcium(II), copper(II), nickel(II), cadmium(II), and zinc(II) ions by nine different commercially available fluorescent indicators (Table 3). For a successful application, it is mandatory that all luminophores can be excited at the same wavelength range between 400 and 500 nm, and that the excitation and emission spectra of all indicators overlap with those of the reference dye encapsulated in the nanobeads. 

Figure 1. Periodic table showing intermetallic compound formation from the reaction of clean metal surfaces with -5000L of SiH4. Temperature required to grow thin films are indicated above the table. Solid areas indicate metals studied in our laboratory, while the cross-hatched areas refer to elements which should be employable based on thin film interdiffusion precedents.
