The strongly concentration dependent 1 H, 14 N and 31 P n.m.r. shifts of some paramagnetic ionic compounds of the general formula [ (C 4 H 9 ) 4 Y] {M [P (C 6 H 5 ) 3 ]X 3 } with Y=N and P, M = Co (II)and Ni (II) are reported and discussed in relation to the recently postulated “ion pairs” in solution. The results indicate a strong direct interaction between the paramagnetic anions and the diamagnetic cations in ion associates.
