Using either an ammoniacal route, the reaction between DyCl3, Na0, and HOR in liquid ammonia, or preferentially reacting Dy(N(SiMe3)2)3 with HOR in a solvent, we isolated a family of dysprosium alkoxides as [Dy(μ-ONep)2-(ONep)] 4 (1), (ONep)2Dy[(μ3-ONep)μ-ONep)Dy(ONep) (THF)]2(μ-ONep) (2), (ONep)2Dy[(μ3-ONep) (μ-ONep)Dy(ONep)-(py)]2(μ-ONep) (3), [Dy3(μ 3-OBut)2(μ-OBut) 3(OBut)4(HOBut)2] (4), [Dy3(μ3-OBut)2(μ-OBu t)3(OBut)4(THF)2] (5), [Dy3(μ3-OBUt)2(μ-OBu t)3(OBut)4(py)2] (6), (DMP)Dy(μ-DMP)4[Dy(DMP)2(NH3)]2 (7), [Dy(η6-DMP)(DMP)2]2 (8), Dy(DMP) 3(THF)3 (9), Dy(DMP)3(py)3 (10), Dy(DIP)3(NH3), (11), [Dy(η6-DIP)(DIP) 2]2 (12), Dy(DIP)3(THF)2 (13), Dy(DIP)3(py)3 (14), Dy(DBP)3(NH3) (15), Dy(DBP)3 (16), Dy(DBP)3(THF) (17), Dy(DBP) 3(py)2 (18), [Dy(μ-TPS)(TPS)2]2 (19), Dy(TPS)3-(THF)3 (20), and Dy(TPS) 3(py)3 (21), where ONep = OCH2CMe3, OBut = OCMe3, DMP = OC6H3(Me) 2-2,6, DIP = OC6H3(CHMe2) 2-2,6, DBP = OC6H3(CMe3) 2-2,6, TPS = OSi(C6H5)3, tol = toluene, THF = tetrahydrofuran, and py = pyridine. We were not able to obtain X-ray quality crystals of compounds 2, 8, and 9. The structures observed and data collected for the Dy compounds are consistent with those reported for its other congeners. A number of these precursors were used as Dy dopants in Pb(Zr0.3Ti0.7)O3 (PZT 30/70) thin films, with compound 12 yielding the highest-quality films. The resulting Pb 0.94Dy0.04(Zr0.3Ti0.7)O3 [PDyZT (4/30/70)] had similar properties to PZT (30/70), but showed substantial resistance to polarization reversal fatigue.
