In inorganic chemistry and materials chemistry, a ternary compound or ternary phase is a chemical compound containing three different elements.
While some ternary compounds are molecular, e.g. chloroform (HCCl3), more typically ternary phases refer to extended solids. Famous example are the perovskites.[1]
Binary phases, with only two elements, have lower degrees of complexity than ternary phases. With four elements, quaternary phases are more complex.
The number of isomers of a ternary compound provide a distinction between inorganic and organic chemistry: "In inorganic chemistry one or, at most, only a few compounds composed of any two or three elements were known, whereas in organic chemistry the situation was very different."[2]
