Chemistry is an experimental science, Application In Synthesis of 3,4,7,8-Tetramethyl-1,10-phenanthroline, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 1660-93-1, Name is 3,4,7,8-Tetramethyl-1,10-phenanthroline
Two new classes of organometallic palladium(II) compounds, namely [Pd(N- N)(CH2NO2)2] and [Pd(L-L)(N-N)(CH2NO2)][PF6] [N-N = 2,2′-bipyridine, 1,10-phenanthroline and their substituted derivatives; L-L = 1,3- bis(diphenylphosphino)propane or N-N] have been synthesized and fully characterized both in the solid state and in solution. The crystal structures of [Pd(phen)2(CH2NO2)][PF6] and of [Pd(dppp)(tmphen)(CH2NO2)][PF6] show a square-planar coordination geometry for the palladium atom and an unexpected monodentate coordination for the N-N ligand. The behavior in solution, investigated by NMR spectroscopy, shows the presence of dynamic processes involving only the N-N molecules. This fluxional behavior is different for [Pd(NN)2(CH2NO2)][PF6] and [Pd(dppp)(N-N)(CH2NO2)][PF6]: in the former it most likely involves the substitution of the nitrogen atom trans to the CH2NO2 moiety by the uncoordinated nitrogen atom of the other N-N ligand; in the latter it may involve the exchange of the two nitrogen atoms at the same coordination site (flipping).
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Application In Synthesis of 3,4,7,8-Tetramethyl-1,10-phenanthroline, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 1660-93-1, in my other articles.
