Die Chemie der Koordinationspolymere hat sich in den vergangenen Jahren rasant entwickelt. Strukturen aus einer Vielzahl molekularer Bausteine mit unterschiedlichen Wechselwirkungen sind mittlerweile zugänglich. Die nächste Stufe ist die chemische und physikalische Funktionalisierung dieser Architekturen durch Einstellung ihrer Porositäten. Dieser Aufsatz konzentriert sich auf drei Aspekte von Koordinationspolymeren: 1) Anwendung von Kristall‐Engineering zum Aufbau poröser Gerüste aus Konnektoren und Linkern (“Nanospace‐Engineering”), 2) Charakterisierung und Katalogisierung porös‐struktureller Funktionalität für Anwendungen in Speicherungs‐, Austausch‐, Trennprozessen etc. und 3) porös‐strukturelle Funktionalität auf der Basis dynamischer Kristallumwandlungen durch Gastmoleküle oder physikalische Reize. Ziel ist es, den aktuellen Stand der Forschung zur Chemie und Physik von und in den Mikroporen poröser Koordinationspolymere vorzustellen.

“…The [Cu 2 (l 3 -CN) 2 ] motifs seem to display the essential role as the main building block in the structure of 1. It is worth mentioned that the number of the SCP containing the rhombic [Cu 2 (l 3 -CN) 2 ] motifs is now growing up [7,9,[18][19][20][21][22][23][24][25][26] presenting a rich collection of structural data on cyanide groups point towards the copper ions producing l 3 -CN units. The previously described 3D-framework of the coordination polymer [Cu 2 (CN) 2 (pip)] (pip = piprazine) even seems to involve l 4 -CN units, i.e.…”

“…The presence of the [Cu 2 (l 3 -CN) 2 ] fragments having two bifurcated cyanide groups leads to bridge the corrugated chains via the bpy ligand developing 3D-network structure. The presence of the rhombic [Cu 2 (l 3 -CN) 2 ] fragment acquires the formation of bent CN groups, Cu2-C4-N12 = 160.20 (3) [18,19,[21][22][23][24][25][26], present in the rhombic motifs. However, the Cu2 ii -C4 ii distance is shorter exhibiting bond length equals to 1.950 Å .…”

A supramolecular coordination polymer (SCP), 3 ?[Cu 2 (CN) 4 (Me 3 Pb) 2 (bpy)], 1, based on the Cu n (CN) m building blocks and (Me 3 Pb) ? cation was synthesized in the presence of an auxiliary rigid-planar bipodal 4,4 0 -bipyridine (4,4 0 -bpy) ligand under ambient conditions. The single crystal X-ray diffraction analysis revealed that the Cu(I) sites acquire T-4 geometry and the lead atom, Pb1 assumes TBPY-5 configuration. The rhombic [Cu 2 (l 3 -CN) 2 ] motifs display the essential role as the main building blocks which are interconnected by the (Me 3 Pb) ? cations to form infinite quasi-planer sheets containing the 24-atomic C 8 N 8 Cu 4 Pb 4 rings. These sheets are connected by the bpy ligands producing 3D-network. The wide vacant space present in the framework of 1 is occupied by a second and identical 3D-framework in that each bpy pillar of one framework passes the center of the 24-atomic ring of the complementary framework producing an inextricably interpenetrated structure. The IR, electronic absorption and emission spectra are also investigated. The SCP 1 is an effective catalyst for methylene blue degradation in presence of H 2 O 2 .

“…[8][9][10][11][12] The copper cyanide system is particularly attractive from the viewpoint of structural engineering because of the previously reported versatility of {CuCN} n structural motifs in accommodating various ligand-imposed geometric requirements. [13][14][15][16][17] On the other hand, organometallic R 3 Sn ＋ (R＝Me or Ph) unit can act as a connecting moiety by axial anchoring to two donor atoms, exhibiting trigonal bipyramidal configuration, creating structures of high dimensionality. [18][19][20][21][22][23][24][25][26][27] It has been shown that organometallic R 3 E ＋ units (R＝Me, Et, n-propyl, n-butyl, phenyl; E＝Sn, Pb) can bridge the cyanometallate anions, M(CN) n q-, in much the same fashion as silver do in SPB 28 except that the greater complexity of the R 3 E ＋ units leads to complicated three-dimensional polymer.…”

Five new metal-organic frameworks (MOFs) of the general composition [Ph 3 SnCu(CN) 2 •L], where L＝ pyrazine (pyz) (1), methylpyrazine (mepyz) (2), 4,4'-bipyridine (bpy) (3), trans-1,2-bis(4-pyridyl)ethene (tbpe) (4) or 1,2-bis(4-pyridyl)ethane (bpe) (5), have been synthesized and characterized to test their potential applications as catalysts. The structures of the MOFs 1-5 mainly consist of Cu(CN) 2 building blocks connected by the Ph 3 Sn cations and the bipodal ligand forming polymeric networks. They exhibit strong fluorescence in the solid state. Also, they are used as heterogeneous catalysts for the degradation of azo-dyes, metanil yellow (MY) by diluted solution of hydrogen peroxide as oxidant. The reaction is first order with respect to MY dye, while the factors affecting the rate constant of the degradation reaction are investigated. The activation parameters of the reaction have been estimated and a possible mechanism has been proposed.
