  2. Zinc diphosphide - Wikipedia

    en.wikipedia.org/wiki/Zinc_diphosphide

    ZnP 2 has a room-temperature tetragonal form that converts to a monoclinic form at around 990 °C. [3] In both of these forms, there are chains of P atoms, helical in the tetragonal, semi-spiral in the monoclinic. [4] This compound is part of the Zn-Cd-P-As quaternary system and exhibit partial solid-solution with other binary compounds of the ...
