ET-IR spectroscopy was employed to investigate the structures of the 1 1 complexes between Li" and the guanidine-substituted azo compounds pyiidine-2-azo-p-phenyltetramethylguanidine and 4,4 -bis(tetramethylguanidine)azoben-zene. Both Li" complexes exist as dimers in acetonitrile solution.The structural chemistry of potassium N,N -di(tolyl)formamidinate complexes has been investigated in detail. These compounds were prepared by deprotonation of the parent Af,N -di(tolyl)formamidines with potassium hydride (Scheme 13). The resulting adducts with either THE or DME display one-dimensional polymeric solid-state structures that exhibit /r-fj fj -coordinated formamidinates. [Pg.192]

A diverse coordination chemistry is emerging for bismuth(III) made possible by a spacious and flexible coordination environment, allowing for coordination numbers in excess of 9. Although the available data are still limited, distinct trends are evident, and the polymeric solid-state features that may be assumed on the basis of high coordination numbers can be mediated by appropriate selection of organic-based ligands. The unusual structural arrangements observed for many types of complex may prove to be representative as the number of examples of such systems increases. [Pg.349]

The -conjugated polyselenophene named PEDOS (182) the analog of poly-3,4-ethylenedioxythiophene (PEDOT) [281], one of the most successful conductive polymers, was obtained from 3,4-ethylenedioxyselenophene (89) using different polymerization techniques. These were oxidative chemical polymerization, solid-state polymerization, transition metal-mediated polymerization, and electrochemical polymerization (Scheme 46) [293, 294], The derivatives of PEDOS having the... [Pg.329]

The second example is the solid organotin compound [Me3SnN(S02Me)2 MesSnOH] for which the single crystal X-ray structure has been determined at two different temperatures, the basic building unit of the polymeric solid state structure being shown in scheme S. [Pg.147]

To minimize the indane, 99, formation, dimerization was conducted in two-phase systems containing toluenesulfonic acid,354 sulfuric acid,355 356 electrophilic transition-metal complexes,357 the polymeric solid-state acid Nafion,358 359 metal oxide solid-state catalysts such as tungstophosphoric acid,360 various zeolites,361 362 mixed oxides,363 and montmorillonite clay in the presence of organic solvents.364 365 The major limitation of the cationic approach, however, is the unavoidable formation of internal isomer 100. Since isomer 100 is inert in radical polymerization, the lower the content of isomer 100, the higher activity of the 98 mixture. Even in the very best cases, its presence is never less than 5—15%. [Pg.542]

The X-ray analysis indicated a zig-zag chain in the solid state with an Sn-O-Si bond angle of 156 ° and perfectly linear Si-O-Si linkage. Interestingly, the polymeric solid-state structure transforms to the six-membered cyclic structure in solution. Equation (3.8.10). [Pg.388]

While it is possible that future polymeric batteries will be all-polymeric solid-state batteries, it is predicted, however, that the most promising solid state batteries will combine polymeric electrolytes with nonpolymeric electrode materials such as TiS2, VeOis, Li or LiAl, the specific capacity of which surpasses that of polyacetylene electrodes. [Pg.597]
