要旨:
ThPt2 crystallizes with unique type of structure (space group I4/mmm, a
= 4.1565(1) A, c = 14.3663(7) A, Pearson symbol tI12), which belongs to
the group of the close packed tetragonal structures. An analysis of the
chemical bonding by the electron localizability approach reveals the
formation of two-dimensional layered platinum anionic substructures
interlinked by strongly polar bonds to Th. Measurements of magnetic
susceptibility, electrical resistivity, and specific heat show ThPt2 to
be diamagnetic with metallic type of electrical conductivity in good
agreement with the calculated electronic structure (N(EF) = 0.9 states
eV(-1) f.u.(-1)).
