WebIn this structure, nickel is octahedral and the sulfide centers are in trigonal prismatic sites. [2] NiS has two polymorphs. The α-phase has a hexagonal unit cell, while the β-phase has a rhombohedral cell. The α-phase is stable at temperatures above 379 °C (714 °F), and converts into the β-phase at lower temperatures. WebAug 27, 2024 · Because a crystalline solid consists of repeating patterns of its components in three dimensions (a crystal lattice ), we can represent the entire crystal by drawing the structure of the smallest identical units that, when stacked together, form the crystal. This basic repeating unit is called a unit cell.
