Magnetization dynamics of a heterometallic Dy-isocarbonyl complex†
Abstract
The reaction of Dy(N(Si(CH3)3)2)3 with three equivalents of HW(CO)3Cp (Cp = cyclopentadienyl) furnished the first structurally characterized isocarbonyl complex of Dy3+, [{CpW(CO)2(μ-CO)}3Dy(thf)5] (1). Solid dilution via cocrystallization with the isostrucutral Y3+ analogue of 1 allowed for the observation of temperature dependent signals in the out-of-phase component of the ac magnetic susceptibility in the presence of an applied dc field. An effective barrier to magnetization reversal of 12.6 cm−1 could be extracted for compound 1 under these conditions.
