In 1893 it was challenged by a relative newcomer, Alfred Werner. Werner called his new theory, "coordination theory".Chain Theory Proposed 1869 The supersession of the most successful pre-Werner theory of the structure of coordination compounds, the so-called Blomstrand-Jørgensen chain theory, by Alfred Werner's coordination theory constitutes a valuable case study in scientific method and the history of chemistry. He is considered one of the founders of coordination chemistry, and is known for the debates which he had with Alfred Werner during 1893-1899. While Jørgensen's theories on coordination chemistry were ultimately proven to be incorrect, his experimental work provided much of the basis for Werner's theories. The coordination theory is an abrupt break with both the Kekulé valence theory and the Blomstrand- Jørgensen chain theory.It assumes that the metal is bound to 6 atoms or groups, creating a radical.

Chain theory was popular for many years after it was proposed in 1869 by Blomstrand.

His interpretations of the l?teo, purpureo, roseo, praseo, violeo, croceo, flavo, and other series of complex salts were made in the light of his extensions and modifications of Blomstrand's chain theory.

In 1850-1870 problems pose about how the structure of complex compounds. The two most convincing theories, “the Blomstrand–Jorgensen chain theory” and “coordination theory” proposed by Alfred Werner, were debated extensively. Blomstrand-Jørgensen theory,[2] and sec- ondly in Alfred Werner's terminology they would have been 'inclusion' compounds. 1889 Diploma of Chemistry, ETH Jørgensen's chain theory Crystal Field & Ligand Field Theories (CFT & LFT) Ligand Filed Theory (LFT): Application of MO theory with focus on metal orbitals 11 Dec 2020 In his version of the theory, Jørgensen claimed that when a molecule would bind via the ammonia chains Blomstrand had described or the Sophus Mads Jørgensen which don't obey the classical valence rules - he knew their stoichiometry - was expressed in the so-called "chain"-theory.

Drawing structures analogous to organic chemicals, they arrived at a cobalt metal bound to long chains of ammonia, with a chlorine at the end of each group. 1869 Blomstrand (Swedia) mengajukan teori rantai untuk struktur kompleks logam. Karena tiap-tiap unsur mempunyai valensi yang tetap, maka Blomstrand dan Jorgensen mengatakan bahwa : Dalam kompleks kobal (III) hanya ada tiga ikatan.
