For the 1st time the self-discipline of contemporary inorganic chemistry has been systematized in line with a plan built by way of a council of editorial advisors and experts, between them 3 Nobel laureates (E. O. Fischer, H. Taube and G. Wilkinson). instead of generating a set of unrelated evaluate articles, the sequence creates a framework which displays the artistic strength of this clinical self-discipline.

S. Gentile, J . White and S. Haddad, Inorg. Chim. Acta, 1975, 13, 149. Phenacyl kojate (13) was found to form crystalline NaX complexes during its preparation in MeOH. PK with CsBr, CsI, RbI, NaNCS, KNCS, RbNCS and CsNCS, and the complexes MX-2PK with NaCl, KCI, RbCl, CsC1, NaBr, KBr, RbBr, NaI and KI. 2PK-2H20186have been solved. The K+ is eight-coordinated through three tridentate PK molecules and two oxygen atoms from the CHzOH of adjacent molecules; the Cs+ is also eight-coordinated due to extensive bridging between the cation, ligand and anion in adjacent molecules; and the Na+ is six-coordinated through one tridentate and one monodentate PK as well as two water molecules.
Dipole terms of a tetrahedral environment for the beryllium. 'H NMR studies on the magnesium and calcium analogues are similarly interpreted. ' The fluorescent properties of a range of beryllium chelates have been monitored with a . 296 The complexes are formulated as having 1: 1 stoichiometry and the ligands are of the general type (55). 2w Stability constants have been reported for a range of beryllium P-ketoamines derived from both salicylaldehyde and acetylacetone precursors. 29872w Salen complexes of beryllium have been reported.
The essential bonding mode of sugars is via the hydroxyl groups, and complexation in solution is due basically to the presence of three sequential hydroxyl groups in a cis-cis state for a five-membered ring, and an ax-eq-ax state for a six-membered ring. These sequences give, for solution complexation, a required equilateral triangle of donor atoms for the cation and favourable entropy factors. " If these criteria are not met, as in D-glucose, the sugar is non-complexing. cis-Inositol (46) with three ax-eq-ax, which can act jointly with three axial hydroxyl groups, serves as an example of an alkaline earth metal complexor.
