Two new hydrides, Li 2 PdH 2 and K 2 PdH 4 , are compared with Na 2 PdH 2 . Both Li 2 PdH 2 and Na 2 PdH 2 are found to be metals and their structures are characterized by linear, formally zero-valent PdH 2 complexes in an alkali atom framework. The

Be2Zr was found to react readily with hydrogen at room temperature and atmospheric pressure to form Be2ZrH1.5. Neutron investigations of Be2ZrD1.5 showed that the compound crystallized in the space group P6/mmm with the zirconium atom at 0,0,0 and th

The appearance of the magnetic double-spiral structure in MnP- and MnAs-based compounds is analysed on the basis of the Heisenberg Hamiltonian with and without Dzyaloshinskii-Moriya term. It is shown that in order to explain the magnetic structures o

X-ray and neutron diffraction have been used to study the hydrogen (deuterium) absorption in the intermetallic compounds Zr2Pd and Ti2Cu both having the tetragonal MoSi2-type structure. Zr2Pd reacts with hydrogen at room temperature to form a hydride
