Содержание слайда: General information about coordination compounds
According to their contents, chemicals are divided into simple substances (H2, Cl2, O2 etc) and compounds (H2O, H2SO4, Na3PO4).
In the late nineteenth century even more complex in structure and composition molecular compounds were produced, they are called complex or coordination compounds.
DEFINITIONS:
Coordination compounds - are chemical compounds, the lattices of which consist of integrated groups formed by ions or molecules able to exist independently.
Coordination compounds - molecular compounds, the formation of which from simple substances is not associated with the occurrence of new electron pairs.
№4 слайд![Werner s coordination theory](/documents_6/3cb72d697aadd907145a913412d466de/img3.jpg)
Содержание слайда: Werner’s coordination theory
According to this theory, in each complex compound there is a сentral ion (complexing), other ions, atoms or molecules - ligands (adends) are placed in a certain order around it.
The Central ion is associated with ligands by donor-acceptor mechanism, it forms an internal area of the complex.
The Central ion is acceptor and ligands are donors of electronic pairs.
It is ionic bond between the inner and outer sphere.
