    • 3 4 dimer (2AB, δ = 30, J = 40 Hz and δ = 45, J = 43 Hz). While the supernatant solution contained complex 3 (s, δ = 42) the isolated precipitate consisted exclusively of 4 (2AB, δ = 30, J = 40 Hz and δ = 45, J = 43 Hz). Evaporation of the total mixture (solution and precipitate) led to a solid which existed only as a dimeric form (4, 2AB, δ = 30, J 40 Hz and δ = 45, J = 43 Hz).
