Mg(x)Mn(1-x)(BH4)2 (x=0-0.8), a cation solid solution in a bimetallic borohydride
Original language description
A solid solution of magnesium and manganese borohydrides was studied by in situ synchrotron radiation X-ray powder diffraction and infrared spectroscopy. A combination of thermogravimetry, mass and infrared spectroscopy, and atomic emission spectroscopywere applied to clarify the thermal gas desorption of pure Mn(BH(4))(2) and a solid solution of composition Mg(0.5)Mn(0.5)(BH(4))(2). Mg(x)Mn((1-x))(BH(4))(2) (x = 0-0.8) conserves the trigonal structure of Mn(BH(4))(2) at room temperature. Manganese isdissolved in the hexagonal structure of alpha-Mg(BH(4))(2), with the upper solubility limit not exceeding 10 mol.% at room temperature. There exists a two-phase region of trigonal and hexagonal borohydrides within the compositional range x = 0.8-0.9 at room temperature. Infrared spectra show splitting of various vibrational modes, indicating the presence of two cations in the trigonal Mg(x)Mn((1-x))(BH(4))(2) solid solutions, as well as the appearance of a second phase, hexagonal alpha-M
