Abstract

The term “Zintl phase” refers to a class of compounds and is used to recognize contributions to the field of solid-state inorganic chemistry by Eduard Zintl. Zintl phases were initially defined as a subgroup of intermetallic phases where the anions or anionic network could be considered formally to be valence satisfied. These compounds are made up of electropositive elements from groups 1and 2 that, in a formal sense, donate their electrons to the electronegative elements from groups 13, 14, and 15, which use them to form the correct number of bonds such that each element has a filled shell. The initial definition has been expanded from the initial binary phases to include ternary phases and further enlarged to include transition metals and rare earth elements in some cases. The compounds that make up this class are described along with the corresponding Zintl anions arising from solution chemistry. Recent results in the field, such as the use of Zintl phases for novel materials, are also described.
