Another method for the determination of the structure of the crystal lattice is SAXS [30,31]. Figure 6 shows the specific SAXS profiles of microsphere film (MC2). The cubic packing values (dl/di) are listed in Table 3. Three clear peaks appeared at 0.35, 0.42, and 0.66 degrees in Fig. 6. The dl/di values of the second and third peaks are >/4/3 and >/U/3, respectively. These values are peculiar to the FC(T structure. Thus, the lattice structure of the microspheres is an estimated FCC. As both... 

Since steric effects can change catalysis (e.g., the above mentione trypsin case), one may still argue that such effects do influence the correl tion between structure and function. However, this case is not so relevant t structure-function correlation since the steric effects establish new structui and the activity associated with this structure is the main subject of ot...

A T structure with the strongest ct-donor D trans to the empty site (I in Scheme 1) is preferred in the case of three pure cr-donor ligands. The presence of a ir-acceptor ligand also makes the T structure more stable. When one of the ligands is a tt-donor, X, a Y structure of type II (Scheme 1) is observed. This structure permits the formation of a w bond between the empty metal d orbital and the lone pair of X. No such tt bond is present in the T structure since all symmetry adapted d orbitals are filled. This partial M—X multiple bond stabilizes Y over T. 

In the mixed case—one ir-donor and a it-acceptor ligand, as in OsHCl(CO) (P1 Pr3)2—the structure III of Scheme 1 (in which the -ir-donor X ligand and the tt-acceptor A ligand are trans to each other) is more stable.22 In a T structure, which...

The solid complex of TV-methylbenzothiazol -2(3H)-selcnonc (mbts) with Te(Ph)Br contains two symmetry-independent molecules, both of which pack in a way that weak dimers through T-T contacts are formed (Figure 29). In molecule A the distance between the Te atom and the neighbouring conjugated ji-system is 365.6 pm, and the Te atom is positioned over the central carbon atom of selenoamide function (Te- Se 413.8 Te- -S 396.1 Te- -N 393.4 pm). In molecule B, the distance from Te to the rc-system is 370.5 pm, and the Te atom is shifted away from the central carbon atom towards the endocyclic sulfur atom (Te- -Se 422.7 Te- -S 390.6 Te- -N 450.2 pm). Related T-T contacts are a general kind of packing for Se and Te-centred T-structures. 

Figure 1.13 Schematic drawing of possible lateral cut of TiCl t structural layer. Chirality of Ti atoms on termination of layer is indicated. ElectroneutraUty conditions impose that metal atoms on this lateral cut are bonded to four Cl atoms bridge bonded to further metal atoms and one Cl atom not bridge bonded and that coordination position is left free. Two nonequivalent coordination positions, which will become available to monomer and growing polymer chain, inward and outward, are indicated by i and o, respectively (see text).
