Abstract

original image

Planned synthesis in solid-state chemistry: Formal substitution of every other Ni atom in HfNi by P led, as predicted, to the synthesis of Hf2NiP, which crystallizes in a monoclinic superstructure of the CrB structure type (structure depicted on the right; • = Ni, ˆ = P, ◯ = Hf). The resulting structural and physical differences between the phases HfNi and Hf2NiP are discussed.
