“…To the best of my knowledge, many Ag(I)–PAH (polycyclic aromatic hydrocarbon) compounds have been reported and show that arenes usually function as neutral π donors to exhibit the η 2 coordination mode . In 4 , the closest Ag···C contact between the neighboring 1D chain is 3.006(5) Å (Ag1···C3 v ), which falls in the normal ranges reported for the related compounds . Although the second closest Ag···C contact [Ag1···C2 v = 3.144(4) Å] is slightly longer as compared to those found for Ag(I)–PAH compound, it is still below the sum of van der Waals radii of Ag(I) ion and carbon atom (3.42 Å) .…”

The ultrasonic reactions of Ag(2)O with benzoguanamine and ancillary carboxylate ligands under the ammoniacal condition gave eight new coordination compounds (CCs), namely, [Ag(4)(bga)(6)(mal)(2)] (1), [Ag(4)(bga)(6)(mlc)(2)] (2), [Ag(bga)(2)(tpa)(0.5)](n) (3), {[Ag(bga)(suc)(0.5)]center dot C(2)H(5)OH}(n) (4), {[Ag(bga)(Pta)(0.5)]center dot CH(3)OH}(n) (5), {[Ag(bga)(ox)(0.5)]center dot C(2)H(5)OH center dot H(2)O}(n) (6), {[Ag(2)(bga)(2)(dnb)(2)]center dot DMF}(n) (7), and [Ag(2)(bga)(2)(pma)(0.5)(H(2)O)](n) (8) (bga = benzoguanamine, H(2)mal = malonic acid, H(2)mlc = maleic acid, H(2)tpa = terephthalic acid, H(2)suc = succinic acid, H(2)pta = phthalic acid, H(2)ox = oxalic acid, Hdnb = 3,5-dinitrobenzoic acid, H(4)pma = pyromellitic acid, and DMF = N,N'-dimethylformamide). All CCs have been characterized by elemental analyses, IR spectra, and single-crystal X-ray diffraction. Compounds 1 and 2 are OD discrete molecules and contain centrosymmetric [Ag(2)(mal)](2) and [Ag(2)(mlc)](2) units, respectively, which are extended to ID supramolecular chains through intermolecule N-H center dot center dot center dot N complementary hydrogen bonds. Compounds 3 and 4 contain similar ID [Ag(2)(tpa)](n) and [Ag(2)(suc)](n) infinite chains incorporating monodentate bga ligand as an ornament. It is noteworthy that the Ag center dot center dot center dot Ag interaction was exclusively observed in the ID chain of compound 4, which may be caused by different coordination environments of the Ag(I) center between 3 and 4. The Ag center dot center dot center dot pi interactions further extend the ID chains into 2D sheet in 4. In 5 and 6, the mu(2)-bga ligands link Ag(I) ions to form ID helical chains, which are further extended by mu(2)-dicarboxylate to 2D 6(3)-hcb net incorporating different dimensions of hexagonal grids. Compound 7 is a ID chain containing [Ag(2)(dnb)(2)] subunits, to which the monodentate and bidentate bga ligands as well as DMF coordinate. Compound 8 is a 2D sheet structure incorporating mu(6)-eta(1):eta(1):eta(1):eta(1):eta(1):eta(0):eta(1):eta(0) pma, monodentate and bidentate bga ligands. The results show that the structural diversity (0D-2D) of the CCs is mainly attributed to the usage of diverse ancillary carboxylate ligands as well as diverse coordination modes of bga ligand. Moreover, the photoluminescence properties of the CCs 1-6 were also investigated in the solid state at room temperature.National Natural Science Foundation of China[21021061, 21071118]; MSTC[2007CB815301

“…The Ag–C bonding is not unusual. References widely reported Ag–C bond lengths in the range of 2.388(5)–2.763(3) Å in Ag(I) polymers for benzene ring C–Ag bonds. − As for Ag(2), it is five coordinated with five oxygen atoms (O3, O5, O5#, O6, O7) from five Hbtec 3– ligands forming a slightly distorted trigonal bipyramid coordination sphere, and the O5, O6, O7, and Ag2 are almost coplanar with only 0.0157 Å off the mean plane. The O3 and O5 occupy the two vertex positions of the trigonal bipyramid coordination sphere.…”

Three novel silver(I) metal−organic coordination polymers constructed from 1,2,3,5-benzenetetracarboxylic acid with different deprotonation degrees, namely, [Ag 2 (H 2 btec)(H 2 O)] (1), [Ag 3 (Hbtec)] (2), and [Ag 4 (btec)](3) (H 4 btec = 1,2,3,5-benzenetetracarboxylic acid), have been synthesized with hydrothermal methods and characterized by elemental analysis, infrared, thermogravimetric analysis, and single crystal X-ray diffraction. The Ag(I) atoms show versatile coordination sphere in the three different complexes and great supramolecular structure difference demonstrated due to the coordination modes change of the H 4 btec ligands. Ag(I) dimers bridged by H 2 btec 2− ligands into a three-dimensional framework was observed in complex 1. An unprecedented talon-like Ag(I) hexamer unit was obtained in complex 2, which acts as a building unit that connects with Hbtec 3− into (5,10)-connected MoGe 2 -type framework. A one-dimensional Ag(I) chain built with Ag(I) tetramer units was demonstrated in complex 3, and each btec 4− ligand bridges six such chains into a three-dimensional framework. However, the weaker argentophilic interactions bridge the talon-like hexamers into a bead-like Ag(I) chain in complex 2, while such weak interactions bridge the zigzag Ag(I) chains into a two-dimensional Ag(I) sheet in complex 3. Photoluminescence, and antibacterial activities of complexes 1−3 were also examined.

“…The monomeric units are characterized by strong donor−acceptor interactions, as evidenced by the short distance (less than 3.5 Å) between the 2,6-di(1 H -imidazol-1-yl)pyridyl plane in 1 4+ and the π surface of the inserted dianion. The “tips” of the interpenetrated dianions protrude from the macrocyclic rings and are linked to other interpenetrated dicarboxylate anions via Ag(I) cation bridges; selected interatomic distances for these contacts are O(2)···Ag(1) = 2.216 Å and O(4)···Ag(1) = 2.138 Å …”

Environmentally Responsive Threading, Dethreading, and Fixation of Anion-Induced Pseudorotaxanes

The tetracationic macrocycle cyclo[2](2,6-di(1H-imidazol-1-yl)pyridine)[2](1,4-dimethylenebenzene) hexafluorophosphate (1(4+)·4PF(6)(-)) acts as a large, flexible "molecular box" that supports the formation of environmentally responsive anion-induced pseudorotaxanes, as well as other extended structures, including metal-linked supramolecular polyrotaxanes. Specifically, the combination of the tetracation 1(4+) and bis-carboxylate guests derived from 4,4'-biphenyldicarboxylic acid and 2,6-naphthalenedicarboxylic acid results in the formation of pseudorotaxanes that respond to changes in environmental stimuli, including pH and temperature. The resulting structures can be "locked into place" via the addition of a metal-linker in the form of Ag(I); this gives rise to an ordered metal-linked polyrotaxane. The interpenetrated constructs described in this article were characterized in solution and in the solid state by one- and two-dimensional ((1)H and NOESY) NMR spectroscopy, as well as by mass spectrometry (ESI-MS) and single-crystal X-ray diffraction methods.
