Solvatotuning of the Field-Induced Slow Magnetic Relaxation through a Single-Crystal-to-Single-Crystal Transformation in Pentanuclear Gadolinium(III)-Nickel(II) Complexes

The partial lossof crystallization water molecules inthe gadolinium(III)-nickel(II)dithiooxalate dodecahydrate [Gd2Ni3(dto)(6)(H2O)(10)]& BULL;12H(2)O (1) to yield the dihydrate derivative [Gd2Ni3(dto)(6)(H2O)(10)]& BULL;2H(2)O (2) provokes significant and reversible changesin the spin relaxation dynamics. This unique single-crystal-to-single-crystaltransformation emerges as a new route toward solvatoswitchable single-moleculemagnets for molecular spintronics and quantum computing.
