Zirconium telluride compounds

Table V-29 Selected thermochemical properties of solid zirconium telluride compounds at 298.15 K. The Gibbs energy of formation data are calculated from the selected enthalpies of formation and entropies.

On the basis of the expected charges on the monatomic ions, give the chemical formula of each of the following compounds (a) manganese(II) telluride (b) barium arsenide (c) silicon nitride (d) lithium bismuthide (e) zirconium(IV) chloride. 

The hydrozirconation of alkynes is a well-established reaction, giving vinylic zirconium species of known regio-and stereochemistry.176 These species react with aryltellurium halides leading to vinylic tellurides with the ( )-stereochemistry 98 (Scheme 61),177,178 so complementing the other general routes to these compounds which give preferentially the (Z)-products (Sections 9.13.5.2.3, 9.13.5.2.5).
