Metal Carboxylates with Open Architectures

TLDR

Inorganic open‑framework materials are dominated by aluminosilicates and phosphates, yet metal carboxylates—mono‑, di‑, and hybrid structures of transition, rare‑earth, and main‑group metals—have emerged as a versatile family capable of forming porous hybrids and nanocomposites. This review discusses the synthesis, structure, and properties of various types of open‑framework metal carboxylates. Certain metal carboxylates exhibit novel adsorption and magnetic properties.

Abstract

The field of inorganic open-framework materials is dominated by aluminosilicates and phosphates. The metal carboxylates have emerged as an important family in the last few years. This family includes not only mono- and dicarboxylates of transition, rare-earth, and main-group metals, but also a variety of hybrid structures. Some of the carboxylates possess novel adsorption and magnetic properties. Dicarboxylates and related species provide an effective means of designing novel hybrid structures with porous and other properties. In some of these structures, the dicarboxylate acts as a linker between two inorganic units. Hybrid nanocomposites are also of particular note, for example, cadmium oxalate host lattices that can accommodate extended alkali-metal halide structures. This Review discusses the synthesis, structure, and properties of various types of open-framework metal carboxylates.
