Structural Classification of Quasi-One-Dimensional Ternary Nitrides

Abstract

This review focuses on the crystal structural features of ternary (mixed-metal) quasi-one-dimensional nitrides i.e., nitrides containing (cation-N 3− ) coordination polyhedra sharing either corners, edges, or faces, arranged in linear chains, and intercalated by a counter ion. The current relevance of these nitrides, and of quasi-one-dimensional compounds in general, lies in the fact that they are closely related to the pure one-dimensional systems (i.e., nanowires), which are vastly researched for their amazing properties closely related to their low dimensionality. A number of these properties were firstly discovered in quasi-one-dimensional compounds, highlighting the importance of expanding knowledge and research in this area. Furthermore, unlike oxides, nitrides and other non-oxide compounds are less developed, hence more difficult to categorise into structural classes that can then be related to other classes of compounds, leading to a fuller picture of structure-properties relationship. Within this context, this review aims to categorise and describe a number of ternary (mixed-metal) quasi-one-dimensional nitrides according to their structural features, specifically, the polyhedra forming the one-dimensional chains.

The Development of Ternary Nitride Chemistry During the Last Few Decades

“…The study of the complex nitride chemistry is even though considerably nascent, with enhanced advancement being made only for the last more than a few years. [2] - [3] Ternary nitrides were first systematically investigated by Juza et al [4] beginning in the 1940s. The preparation of ionic and covalent ternary and quaternary nitrides gives numerous fascinating tasks for the synthetic inorganic scientific community.…”

“…The critical understanding of the color film structure must also be comprehensively elucidated. Compared to other inorganic layers, metal oxides are cheaper and easier to synthesize and characterize [ 34 ]. This enables them to be potential materials to be adopted into applications that can be used anywhere in the environment.…”
