Iron(II) cage complexes [Fe{(1-X, 8-Y)-sar}]2+ (X = Y = H, NH2, or NH3+, or X = Me, Y = H, sar = 3,6,10,13,16,19-hexa-azabicyclo[6.6.6]icosane) show high-spin ( 5T2g origin) ⇌ low-spin (1A1g origin) equilibria in solution, characterised by measurements of magnetism and visible and 1H n.m.r. spectra.
