Sousa, Electrochemical synthesis of metallic complexes of bidentate thiolates containing nitrogen as an additional donor atom
5] fragments react quickly with any available donor atom
to yield a M[(CO).
When atoms of these two kinds interact, a re-arrangement of the electron distribution occurs; an electron from the donor atom
migrates to the acceptor atom thereby making the acceptor atom negatively charged and the donor atom
These 16-electron M(CO)5 fragments react quicklywith any available donor atom
to form a M[(CO).
There is mounting evidence that the molecules that are best at this contain soft donor atoms
to the metals.
Highly unusual di- and tri-metallic Ln-SMMs are proposed in which the metals are bridged by radicals with heavy Group 15 donor atoms
For example kryptofix 222 having nitrogen and oxygen donor atoms
has drawn interest due to % its ability to selectively bind ions especially alkali and alkaline earth metal cations [8-10].
The presence of both hard nitrogen and soft sulphur donor atoms
permits coordination with a wide range of transition and non-transition metal ions yielding stable and extremely coloured metal complexes, some of which have exhibited interesting physico-chemical [2-4] and potentially beneficial chemotherapeutic properties [5-8].
The thermodynamic characteristics of doubly charged ions of 3d metals with ligands containing oxygen, nitrogen, and fluorine donor atoms
Forty sections treat ligand whose donor atoms
come from a single group in the priodic table, ligands with mixed donors, and multidentate macrocyclic ligands.
Due to the fascinating structure with multiple N and O donor atoms
, it may be potential applications in organic light emitting diodes (OLED).
