Systematic synthesis

The systematic synthesis and spectral examination of a large series of complexes, M(ol)n, ra = 1-3, M = Ni or Pd, has been performed (140 -142), with special reference to the optical spectra of the products, again affirming the usefulness of the technique for observing spectral trends as a function of substituent (see later). A number of interesting points emerged from this study, some of which have already been alluded to. The optical data for the nickel and palladium complexes respectively are reported in Tables XVI and XVII. 

During the course of an attempted recrystallization of this complex from benzene containing chlorinated impurities the solution was exposed to light. The crystalline compound that formed from this solution was identified by X-ray crystallography as Mo(TPP)(Ph)Cl (Fig. 3). The complex contains Irons phenyl and chloro ligands, and the Mo—C and Mo—N4 plane distances are 2.241(1) and 0.125 A, respectively. A systematic synthesis of the complex could not subsequently be developed and consequently other spectroscopic and magnetic data were not collected.

In 19851 a gallophosphate with a porous framework structure was reported by Parise (ref. 4). This was followed by the systematic synthesis of the GaPO family (refs. 5,6) in our laboratory and the structural characterization of several single crystals of the compounds (refs. 7 11).

No systematic synthesis of any cluster has been devised as yet. The only generalizable statement in cluster preparations is that clusters may be formed when a coordinative-ly unsaturated metal species is generated in the absence of donor ligands 231, 241). Consequently, clusters are often formed as unexpected products in reactions where the formation of unsaturated metal species is imaginable but not obvious. Whereas these obscure formations of clusters cannot be treated in this chapter, some preparative procedures used more often deserve comment.

The systematic synthesis of non amphiphilic l.c.-side chain polymers and detailed physico-chemical investigations are discussed. The phase behavior and structure ofnematic, cholesteric and smectic polymers are described. Their optical properties and the state of order of cholesteric and nematic polymers are analysed in comparison to conventional low molar mass liquid crystals. The phase transition into the glassy state and optical characterization of the anisotropic glasses having liquid crystalline structures are examined.
