✦ Synopsis

Vanadyl chloride, which is insoluble in toluene, can be made to dissolve in the presence of a n excess of triethylphosphine (P;V B 4). The solution exhibits the ESR spectrum shown in Fig. l a . The intensity of the signal corresponds to essentially all the vanadium present in the solution. The signal is characteristic of the interaction of the unpaired electron of V(iv) with the j l V nucleus (nuclear spin I = 7/2) and with two equivalent 3LP nuclei (I = 1/2), the latter interaction being responsible for the triplet splitting (1 : 2: 1) of the eight vanadium lines. The ESR data, which are shownIin Tablell, line 1, are consistent with structure ( I ) or (2).
