摘要: Abstract The new phosphide ScNip can be synthesized by arc-melting of ScP and Ni, or Sc with NiP. lattice constants, as obtained from the bulk sample, area=6.3343(8) A,b=3.7375(7) A,c=7.0917(8), andV=167.89(4) A3. ScNiP crystallizes in Co2Si structure type. Although one might assign trivalent state to Sc, corresponding a formal ionic formula Sc3+Ni±0P3−, contains Sc–Sc bonds shows weak metallic properties, expected based on extended Huckel calculations.
