Synthesis and Structural Investigation of Metal Hydride, Y(Mn1-xFex)2Hy (x ≤ 0.3, 4.0 ≤ y ≤ 4.5) and Complex Hydride, Y(Mn1-xFex)2H6

Abstract

It Has Been Reported that the Metal Hydride, Ymn2hy (y≤ 4.5), Wherein the Hydrogen Atoms Are Located into the Interstitial Sites, Transformed into a Complex Hydride, YMn2H6, Containing Complex Anions, [MnH6]5-. We Investigated the Possibility of Synthesizing the Complex Hydride, Y(Mn1-xFex)2H6(x≤ 0.3), where Mn Atoms Were Partially Substituted by Fe. As a Result, the Transformation into the Complex Hydride, Y(Mn1-Xfex)2H6, Was Successfully Realized forx≤ 0.10 upon the Hydrogenation of the Metal Hydride, Y(Mn1-xFex)2Hy(y= 4.4 and 4.5), under 50 Mpa H2, much Lower than the Previously Reported Value of 1 GPa. Our Structural Investigation Suggested that the Fe Substitution in Y(Mn1-xFex)2H6(x≤ 0.10) Resulted in the Form of Complex Anions, I.e., [MnH6]5-Were Partially Substituted by [FeH6]4-.
