Highly sensitive magnetic effects induced by hydrogen-bonding interactions in a high-spin metallosupramolecular Fe(4) (II) [2x2] grid-type complex.
A sensitive magnetic nanoprobe: Hydrogen-bonding interactions are reflected with great sensitivity in the (1)H NMR spectra of a high-spin multinuclear Fe(4) (II) [2x2] grid-type complex (see scheme) and the measured shifts can be used to evaluate the hydrogen-bond donating ability. The grid complex also represents a prototype of a very sensitive magnetic nanoreceptor for the detection of very small changes around a magnetic center.
