Various types of metal complexes based on chelating β-diketones and their structural analogues

“…96 ± 99 In this reaction, o-hydroxyazomethine chelates 68 act as ligands. 10,99,100 Similar procedures have been used to prepare bi- 101,102 and trinuclear 103 complexes based on lanthanide (La, Gd) b-diketonates and transition metal N,N H -bisacetylacetone iminates.…”

Aluminiumorganic compounds of some metaldioximates

“…IR absorptions in this range of aluminiumorganic derivatives of coordinated DMGH 2 and DPGH 2 exhibit bands at about 490, 520 and 680 cm À1 . These absorption bands 9,10,28 can be attributed to the Al-O, M-N and M-C bonds.…”

“…The coordination of the dioxime with these metals determines the screening of the ligand characteristic properties. The lack of reactivity of the OH groups in the coordinated oximes was caused by the intramolecular hydrogen bonds, 10,12,14,17,[23][24][25][26][27] O -HÁ Á ÁO, existing in these compounds.…”

Molecular nanotechnologies of gelatin-immobilization using macrocyclic metal chelates

“…The so-called template synthesis ( 7 – 10 ), which allows one, in principle, to obtain macrocyclic and supramolecular compounds of any complexity from rather simple fragments (the so-called ligand synthons or ligsons) play an important role in the synthetic methods of modern molecular nanotechnology called self-assembly. In the above version of self-assembly, a particular metal ion with a certain electron structure as a kind of ‘pattern’ which is sometimes called a template center or simple template, provides the formation of metal complexes from the corresponding ligsons.…”
