A. Bouamrane et al., Standard enthalpies of formation of sodium-magnesium hydride and hydridofluorides NaMgH3, NaMgH2F and NaMgF2H, THERMOC ACT, 326(1-2), 1999, pp. 37-41
The standard enthalpies of formation of NaMgH3 and NaMgH2F were determined
by calorimetry using their reaction with hydrochloric acid aqueous solution
(0.5 M HCl):
Delta(f)H(0) (NaMgH3, cr, 298 K) = -(231 +/- 4) kJ mol(-1)
Delta(f)H(0)(NaMgH2F, cr, 298 K) = -(720 +/- 8) kJ mol(-1)
The standard enthalpy of formation of NaMgF2H was estimated on the basis of
the experimental measurements and on the value of sodium-magnesium fluorid
e (NaMgF3) noted in the literature:
Delta(f)H(0)(NaMgF2H, cr, 298 K) = -(1221 +/- 7) kJ mol(-1).
