“…Also, the oxalate anion is often a bridging ligand in construction of homo-or heterometallic compounds with open-framework architectures [1] and interesting magnetic and optical properties [2]. The tetra(oxalato)metalates [M(C 2 O 4 ) 4 ] n-(M = Zr IV [3,4], Hf IV [3,5], Nb IV [6,7], U IV [8,9], Yb III [10]) involve transition metals in higher oxidation states and with higher coordination numbers. The [M(C 2 O 4 ) 4 ] nanion is often used as a base-building unit [11] for the formation of several types of homo/heterometallic supramolecular (3D) nano-porous architectures with zeolitic properties, where the central metal atom adopts dodecahedral (DD) or square-antiprismatic (SA) coordination [12,13].…”

The compound [NH 4 ][(CH 3 ) 2 NH 2 ] 2 [Ta(C 2 O 4 ) 4 ]Á 2H 2 O has been synthesized and characterized by elemental and TG/DTA analyses, IR spectroscopy and by the singlecrystal X-ray diffraction study. The structure comprises the [Ta(C 2 O 4 ) 4 ] 3-anion, NH 4 ? and [(CH 3 ) 2 NH 2 ] ? cations and crystallization water molecules. The Ta atom is octacoordinated by oxygen atoms from four bidentate oxalate groups forming a coordination polyhedron close to the triangular dodecahedron. The charge-assisted hydrogen bonds from both cations connect the [Ta(C 2 O 4 ) 4 ] 3-anions into a threedimensional framework.

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.
