PURELY SILICEOUS HFI-tvoe ZEOLITES. Among the templating cations which were uaed, P R proved to be the moat efficient for easy and fast crystallization. In Table IT are given the crystallographic oharacteriatica of the obtained siliceous HFI-type zeolites (16) aa a function of the template. 

The introduction of lattice centering makes the treatment of crystallographic symmetry much more elegant when compared to that where only primitive lattices are allowed. Considering six crystal families Table 1.12) and five types of lattices Table 1.13), where three base-centered lattices, which are different only by the orientation of the centered faces with respect to a fixed set of basis vectors are taken as one, it is possible to show that only 14 different types of unit cells are required to describe all lattices using conventional crystallographic symmetry. These are listed in Table 1.14, and they are known as Bravais lattices. ... 

Ferroelectric perovskites have their Ciuie temperatrrre scattered over the wide temperatrrre range (e g. -260°C for KTa03 and 490 C for PbTi03). Ferroelectric phases exhibit mostly tetragonal, rhombohedral or orthorhombic crystallographic symmetry. Paraelectric phase is of the cubic m3m symmetry. For ferroelectric characteristics of perovskite crystals see Tables 7.11 and 7.12. 

The quantitative relationship (stoichiometry) of calcium to phosphate in Ca-P salts is essential for several material characteristics as strength, solubility, and crystal structure. Table 38.1 lists the main Ca-P compounds for biomedical applications. From a crystallographic point of view, the most stable form of... 

Table 2 shows the results of our preliminary calculations of the pKa of the Cys403 residue, for several different models of the enzyme, based on two structures available from the PDB. In the case of the YPT structure, a crystal water molecule is close to Cys403 and was included in some of the calculations as part of the protein (i.e. it was treated with the same internal dielectric as that of the protein). Simulations denoted as -I-H2O in Table 2, include a crystallographically resolved, buried water molecule, situated 3.2lA from...

For crystallographic data, see Table I. The compounds of the type CuTeX and CuTe X (X = Cl, Br, or I), respectively, are isotypic, and their crystal structures have been determined. Copper has the oxida-... 

Table XXI shows the crystallographic data as far as they are known. The structures of the three sulfide iodides have been determined by single-crystal studies. Powder patterns of the 8n(IV) compounds not given here have been reported elsewhere (24).

The crystal structures of the mesogenic compounds CBn were reported by different authors [45-51]. Selected crystallographic and molecular data of the investigated compounds CBn are summarised in Table 1. Only the crystal structures of some compounds will be discussed here. 

The synthesis of the mesogenic trans-4-n-alkyl-(4 -cyanophenyl)-cyclohexanes (PCHn) was described by Eidenschink et al. [65] in 1977. Most of the compounds exhibit a nematic phase close to room temperature. The chemical structure of the mesogenic PCHn is shown in Fig. 6. During the past few years, the crystal structures of some mesogenic phenylcyclohexanes were published [66-70]. Selected crystallographic and molecular data of the investigated compounds PCHn are presented in Table 4.
