Abstract:
The coordinative behaviour of the bis(trifluoromethylsulfonyl)amide (NTf2-) anion was studied in terms of its interaction with the labile [Pd(terpyridine)Cl]Cl complex. Among various attempts to coordinate NTf2- to the Pd(II) centre, the complexes [Pd(terpyridine)NO3]NTf2 and [Pd(terpyridine)H2O](NTf2)2 were isolated and characterized. The crystallographic data for these complexes are presented and the possible coordination of the NTf2- anion to the metal centre is discussed in reference to DFT predictions.

Chemical Shift: Internal References and Solvent Effects
The internal reference compound generally used in NMR spectroscopy is tetramethylsilane (TMS). TMS is preferred because it is chemically inert, soluble in NMR solvents, and easily removable. Also, the highly shielded methyl protons in TMS yield an intense...
¹H NMR: Complex Splitting
Splitting diagrams or splitting tree diagrams are routinely used to depict such complex couplings. While drawing splitting diagrams, the splitting with the larger coupling constant is usually applied first.
