Abstract

It has been reported that the metal hydride, YMn₂H_y (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(Mn_1-xFe _x)₂H₆ (x ≤ 0.3), where Mn atoms were partially substituted by Fe. As a result, the transformation into the complex hydride, Y(Mn_1-xFe_x)₂H₆, was successfully realized for x ≤ 0.10 upon the hydrogenation of the metal hydride, Y(Mn_1-xFe_x)₂H_y (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(Mn_1-xFe_x)₂H₆ (x ≤ 0.10) resulted in the form of complex anions, i.e., [MnH₆]^5- were partially substituted by [FeH₆]^4-.
