Abstract
99 Ru Mössbauer spectra have been recorded at 4.2 K for the ternary hydrides M2RuH6(M = Ca, Sr, Eu, or Yb), and are consistent with the presence of diamagnetic ruthenium(II) in all four compounds. 151Eu Mössbauer measurements reveal that Eu2RuH6 contains magnetically ordered EuII; the internal field follows an S= 7/2 Brillouin function with a Curie temperature of 28.0 ± 0.2 K and a saturation value of B= 25.7 ± 0.1 T at 4.2 K. The results are discussed briefly in terms of the bonding in these compounds and the magnetic exchange interactions in Eu2RuH6.Keywords
