“…Four are coming from two oxalate equatorial ligands while the two others are belonging to two oxalates of neighboring chains. 51 Nevertheless, copper atom surrounded by three coordinated oxalate groups is known in 2D oxalate-based magnets 16 and in a 1D helical chain 61 obtained by oxidation of a mixture of copper(II), vitamin C, and 2-diethylaminoethanol in the presence of H 2 O 2 . In the former case, no singlecrystal diffraction data are available.…”

Three-dimensional oxalate-based {[Ru(bpy) 3 ][Cu 2x Ni 2(1-x) (ox) 3 ]} n (0e x e 1, ox ) C 2 O 4 2-, bpy ) 2,2′bipyridine) were synthesized. The structure was determined for x ) 1 by X-ray diffraction on single crystal. The compound crystallizes in the cubic space group P4 1 32. It shows a three-dimensional 10-gon 3-connected (10,3) anionic network where copper(II) has an unusual tris(bischelated) environment. X-ray powder diffraction patterns and their Rietveld refinement show that all the compounds along the series are isostructural and singlephased. According to X-ray absorption spectroscopy, copper(II) and nickel(II) have an octahedral environment, respectively elongated and trigonally distorted. As shown by natural circular dichroism, the optically active forms of {[Ru(bpy) 3 ][Cu x Ni 2(1-x) (ox) 3 ]} n are obtained starting from resolved ∆-or Λ-[Ru(bpy) 3 ] 2+ . The Curie-Weiss temperatures range between -55 (x ) 1) and -150 K (x ) 0). The antiferromagnetic exchange interaction thus decreases when the copper contents increases in agreement with the crystallographic structure of the compounds and the electronic structure of the metal ions. At low temperature, the compounds exhibit complex long-range ordered magnetic behavior.

Offene Metallcarboxylat‐Architekturen

Alumosilicate und Metallphosphate sind die wichtigsten Beispiele für anorganische Materialien mit offenen Gerüsten. In den letzten Jahren stieß zu dieser Gruppe die Familie der Metallcarboxylate, zu der nicht nur Mono‐ und Dicarboxylate von Übergangs‐, Seltenerd‐ und Hauptgruppenmetallen, sondern auch eine Vielzahl von Hybridstrukturen zählen. Einige Carboxylate weisen neuartige magnetische Eigenschaften und Adsorptionseigenschaften auf. Mithilfe von Dicarboxylaten und verwandten Verbindungen kann man effektiv neue poröse Hybridstrukturen erhalten. In einigen dieser Strukturen verbrücken die Dicarboxylateinheiten zwei anorganische Einheiten. Bemerkenswert sind auch die neuen Hybridnanokomposite, in denen Gitter aus Cadmiumoxalat als Wirte für aufgeweitete Alkalimetallhalogenidstrukturen dienen. In diesem Aufsatz beschreiben wir die Synthesen, Strukturen und Eigenschaften von Metallcarboxylaten mit verschiedenartigen offenen Gerüsten.

Metal Carboxylates with Open Architectures

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.
