Chemistry is an experimental science, SDS of cas: 123640-38-0, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 123640-38-0, Name is 2,6-Di(1-pyrazolyl)pyridine
Reversible five-coordinate ? six-coordinate transformation in cobalt(II) complexes
The heterocyclic ligands 2,6-bis(pyrazol-1-yl)pyridine (L1) and 2,6-bis(benzimidazol-2-yl)pyridine (L2) and their cobalt(II) complexes were synthesized. The blue five-coordinate complex [Co(L1)Cl2] isolated initially from the reaction mixture rapidly absorbed water vapour from the atmosphere to yield the pink six-coordinate complex [Co(L1)(H2O)3]Cl2. This change is reversible upon desiccation or transferring [Co(L1)(H2O)3]Cl2 into acetonitrile. The five coordinate complex [Co(L2)Cl2], however, remains stable under similar conditions. The structures of the complexes [Co(L1)Cl2], [Co(L1)(H2O)3]Cl2 and [Co(L2)Cl2] have been determined by x-ray crystallography. The magnetic susceptibilities and the electronic spectra for [Co(L1)Cl2], [Co(L2)Cl2] and [Co(L1)(H2O)3]Cl2 are presented.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. SDS of cas: 123640-38-0, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 123640-38-0, in my other articles.
