The tetrabromonickelate anion contains a doubly-charged nickel atom (Ni2+) surrounded by four bromide ions in a tetrahedral arrangement. The formula is...

a polymer consisting of octahedral Ni centers. The corresponding tetrabromonickelates are also thermochromic with a lower transition temperatures. The...

"nickelates". These include the chloronickelates, fluoronickelates, tetrabromonickelates, tetraiodonickelates, cyanonickelates, nitronickelates and other...

With four bromide atoms nickel(II) forms a series of salts called tetrabromonickelates. Nickel iodide NiI2 is black, also crystallising in the cadmium chloride...
