Coordination Aspects in Modern Inorganic Chemistry

“…Werner´s classification according to ligand nature [6,17] 4) According to electronic configuration of a complexformer.…”

“…According to this classification, metal complexes can be divided in five types [17]: molecular complexes, metallocyclic complexes (chelates), complexes with multi-central bonds, di-and polimetallic complexes and supramolecular coordination complexes. This classification [14,17] comprehends all known types of metal complexes and concentrates attention on peculiarities of types of molecules in complexes and not of their separate parts [3,16,18].…”

“…Reactivity of metal complexes is an important area of coordination chemistry [47][48][49][50], including reactions on coordinatively-unsaturated donor centers 52, 59 [14,17,25,26] or metals complex-formers 54-57 [14, 41,42], as well as reactions of self-assembling, leading to various supramolecular structures [19][20][21]. Reactions of coordinated inorganic and organic ligands are of the high interest.…”

“…We note that some supramolecular structures may contain, as central atoms, not only cations 1, but also anions, for instance halides 2 (details in [7][8][9][10][19][20][21] Werner´s complexes (the basis of coordination chemistry in the end of XIX and beginning of XX century) belongs to this type of complexes [6,17]. When p or q=0, the complexes contain the same ligands (homoleptic complexes); if q 0, they contain distinct ligands.…”
