TL;DR: In this paper, the synthesis and X-ray characterization of N 9 and N 6 -decyladenine hydrochloride salts were reported, where the latter exhibits interesting anion-π interactions, which are responsible for crystal packing.

TL;DR: A ternary complex [Cu(gg)(bzim)·3H 2 O ( 1 ) (gg = glycyl glycine(2−), bzim = benzimidazole) has been crystallized from aqueous solution as mentioned in this paper.

TL;DR: The ternary complexes (glycylglycinato)(isocytosine)copper(II) dihydrate 1 and 6-methylisocyto-isoceto-copper (II) monohydrate 2 have been characterised by X-ray diffraction, electrochemistry and optical, ESR and IR spectroscopy as discussed by the authors.
Abstract: The ternary complexes (glycylglycinato)(isocytosine)copper(II) dihydrate 1 and (glycylglycinato)(6-methylisocytosine)copper(II) monohydrate 2 have been prepared and characterised by X-ray diffraction, electrochemistry and optical, ESR and IR spectroscopy. The two compounds are slightly distorted square planar, with the four co-ordination sites occupied by the tridentate glycylglycine dianion [O(7), N(13) and N(10)] and N(3) of the pyrimidine base. An additional weak axial interaction exists between an oxygen of a water molecule O(W1) and the copper atom [Cu· · ·O(W1) distances 2.74 and 2.70 A respectively]. Spectroscopic and electrochemical data are in accord with the crystal structures. Although both compounds exhibit irreversible oxidation processes, the oxidation of CuII to CuIII is best performed with the isocytosine complex.

TL;DR: The CH/π interaction is a kind of hydrogen bond operating between a soft acid CH and a soft base π-system (double and triple bonds, C6 and C5 aromatic rings, heteroaromatics, convex surfaces of fullerenes and nanotubes) as discussed by the authors.
Abstract: The nature and characteristics of the CH/π interaction are discussed by comparison with other weak molecular forces such as the CH/O and OH/π interaction. The CH/π interaction is a kind of hydrogen bond operating between a soft acid CH and a soft base π-system (double and triple bonds, C6 and C5 aromatic rings, heteroaromatics, convex surfaces of fullerenes and nanotubes). The consequences of CH/π hydrogen bonds in supramolecular chemistry are reviewed on grounds of recent crystallographic findings and database analyses. The topics include intramolecular interactions, crystal packing (organic and organometallic compounds), host/guest complexes (cavity-type inclusion compounds of cyclodextrins and synthetic macrocyclic hosts such as calixarenes, catenanes, rotaxanes and pseudorotaxanes), lattice-inclusion type clathrates (including liquid crystals, porphyrin derivatives, cyclopentadienyl compounds and C60 fullerenes), enantioselective clathrate formation, catalytic enantioface discriminating reactions and solid-state photoreaction. The implications of the CH/π concept for crystal engineering and drug design are evident.

TL;DR: This review describes a multidimensional treatment of molecular recognition phenomena involving aromatic rings in chemical and biological systems that facilitates the development of new advanced materials and supramolecular systems, and should inspire further utilization of interactions with aromatic rings to control the stereochemical outcome of synthetic transformations.
Abstract: This review describes a multidimensional treatment of molecular recognition phenomena involving aromatic rings in chemical and biological systems. It summarizes new results reported since the appearance of an earlier review in 2003 in host-guest chemistry, biological affinity assays and biostructural analysis, data base mining in the Cambridge Structural Database (CSD) and the Protein Data Bank (PDB), and advanced computational studies. Topics addressed are arene-arene, perfluoroarene-arene, S⋅⋅⋅aromatic, cation-π, and anion-π interactions, as well as hydrogen bonding to π systems. The generated knowledge benefits, in particular, structure-based hit-to-lead development and lead optimization both in the pharmaceutical and in the crop protection industry. It equally facilitates the development of new advanced materials and supramolecular systems, and should inspire further utilization of interactions with aromatic rings to control the stereochemical outcome of synthetic transformations.
