“…[23] Intramolecular hydrogen-bonding interactions [C(9)-H(9A)···N (12) A method for preparing bimetallic compounds from hexacyanoferrate(iii) under hydrothermal conditions has been reported previously. [24] Upon comparing the structure of 4 with the reported compound [Fe(bipy) 2 (CN) 4 Cu 2 ], it can be seen that the latter compound is constructed by alternately fused 6-and 10-metal-membered rings to form an ABAB pattern layer instead of the twofold interpenetrating structure found in compound 4.…”

“…As copper normally adopts three-, four-, five-, or sixfold coordination to form diverse geometric structures, much research has focused on the copper cyanide system from the viewpoint of structural engineering. [4,5] Helical structures have received special attention in the past decades as helicity is an essential element for bioactivity and also due to their potential applications in asymmetric catalysis and nonlinear optical materials. [6] To date, quite a few single-or double-helical chains have been generated, [7][8][9] with most helical polymers being obtained by using chiral ligands [10,11] or oligopyridines and other optically active ligands.…”

The hydrothermal reaction of Cu(NO3)2·3 H2O, K3Fe(CN)6, and 1,10‐phenanthroline (1,10‐phen) or 2,2'‐bipyridine (2,2'‐bpy) gives rise to the three one‐dimensional helical‐chain complexes [Cu2Fe(CN)4(1,10‐phen)3]n·0.5n H2O (1), [Cu3(CN)3(1,10‐phen)3]n (2), and [Cu3(CN)3(2,2'‐bpy)3]n (3), and the two‐dimensional layer complex [Cu3Fe(CN)5(2,2'‐bpy)2]n (4). The structure of 1 contains a cyanide‐bridged CuI···FeII···CuI chain in which the two copper and one iron centers exhibit different coordination environments. The structures of 2 and 3 are both monometallic. Complex 4 is constructed alternately from fused 6‐ and 14‐metal‐membered nonplanar centrosymmetric rings that form a 2D layer architecture.

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.

“…Growth of individual 2 D polymers can proceed with opposite relative orientations of the 2-methyl groups during the self-assembly process and this leads to observation of positional disorder in the macroscopic space group P 1. In view of the fact that both 1 : 1 and 2 : 1 CuSCN based coordination networks with the parent spacer ligand pyrazine are now known [17,18], we decided to also study the reaction of CuSCN with 2 Mepyz at the latter molar ratio. This does, indeed, afford a 2 : 1 polymer (Fig.…”

Non-centrosymmetric one-to three-dimensional CuSCN-based coordination polymers with substituted pyrazine or pyrimidine spacer ligands can be prepared by self-assembly in acetonitrile solution at 100°C. Both 1 I [CuSCN(2 NCpyz) 2 ] (1) (2 NCpyz = 2-cyanopyrazine) and 1 I [CuSCN(4 HOpym) 2 ] (3) (4 HOpym = 4-hydroxypyrimidine) contain single zigzag CuSCN chains as their central backbone and crystallise in polar space groups (monoclinic Cm and orthorhombic Ama2). In 2 I [(CuSCN) 2 (l-2 Mepyz)] (2) (2 Mepyz = 2-methylpyrazine), 1 I [(CuSCN) 2 ] staircase double chains are connected by bridging 2 Mepyz ligands to afford a lamellar polymer (triclinic P 1). Whereas 2 I [CuSCN(5 Brpym)] (4) (5 Brpym = 5-bromopyrimidine) with its honeycomb 2 I [CuSCN] layers is chiral (monoclinic P2 1 ), both 3 D polymers 3 I [(CuSCN) 2 (l-pym)] (5) and 3 I [(CuSCN) 3 (l-4 Mepym)] (6) (4 Mepym = 4-methylpyrimidine) contain polar coordination networks (orthorhombic Fdd2 and monoclinic Pc). The CuSCN framework in (5) consists of thiocyanate bridged 1 I [CuS] chains, that in 6 of interlocked 2 I [CuSCN] and 2 I [Cu 2 S(SCN)] sheets. Nichtzentrosymmetrische Koordinationspolymere mit CuSCN und substituierten Pyrazin-und Pyrimidinliganden Inhaltsu È bersicht. Nichtzentrosymmetrische ein-bis drei-dimensionale Koordinationspolymere mit CuSCN und substituierten Pyrazin-oder Pyrimidinliganden ko È nnen durch Selbstorganisation in Acetonitrillo È sung bei 100°C dargestellt werden. Sowohl 1 I [CuSCN(2NCpyz)] (1) (2 NCpyz = 2-Cyanopyrazin) als auch 1 I [CuSCN(4 HOpym) 2 ] (3) (4 HOpym = 4-Hydroxypyrimidin) enthalten einfache zickzackartige CuSCN-Ketten als zentrales Ru È ckgrat und kristallisieren in polaren Raumgruppen (monoklin Cm bzw. orthorhombisch Ama2). In 2 I [(CuSCN) 2 (l-2 Mepyz)] (2) (2 Mepyz = 2-Methylpyrazin), erzeugt die Verknu È pfung von treppenartigen Doppelketten 1 I [(CuSCN) 2 ] durch 2 Mepyz-Bru È ckenliganden ein schichtartiges Polymer (triklin P 1). Wa È hrend 2 I [CuSCN(5 Brpym)] (4) (5 Brpym = 5-Bromopyrimidine) mit seinen wabenartigen Schichten 2 I [CuSCN] chiral (monoklin P2 1 ) ist, weisen die dreidimensionalen Polymere 3 I [(CuSCN) 2 (l-pym)] (5) and 3 I [(CuSCN) 3 (l-4 Mepym)] (6) (4 Mepym = 4-Methylpyrimidin) polare Koordinationsnetzwerke (orthorhombisch Fdd2 bzw. monoklin Pc) auf. Das CuSCN-Geru È st von 5 besteht aus SCN-verbru È ckten 1 I [CuS]-Ketten, das von 6 aus miteinander verbundenen 2 I [CuSCN]-und 2 I [Cu 2 S(SCN)]-Schichten.
