2,2'-Bipyridine Derivatives as Halogen Bond Acceptors in Multicomponent Crystals.

ABSTRACT: In this work, we present a systematic study of the halogen bonding potential of different 2,2'-bipyridine derivatives in the synthesis of cocrystals by using selected perfluorinated iodobenzenes and N-haloimides as halogen bond donors. These halogen bond acceptor molecules were chosen to explore how different substituents on 2,2'-bipyridine affect halogen bond formation. Out of 24 combinations, we obtained only 8 cocrystals by using two methods, liquid-assisted grinding and crystallization from the solution. Of those 8 cocrystals, one has already been described in the literature. As expected, structural data revealed that 2,2'-bipyridine derivatives act as ditopic halogen bond acceptors in all structures. Dominant interactions in 7 of the cocrystals are I···N or Br···N halogen bonds, while in the one remaining cocrystal it is the I···C(π) halogen bond.

Structural Examination of Halogen-Bonded Co-Crystals of Tritopic Acceptors.

Project description:A series of tritopic N-heterocyclic compounds containing electrostatically and geometrically equivalent binding sites were synthesized and subjected to systematic co-crystallizations with selected perfluoroiodoarenes in order to map out their structural landscapes. More than 70% of the attempted reactions produced a co-crystal as indicated by IR spectroscopy. Four new crystal structures are reported and in all of them, at least one potential binding site on the acceptor is left vacant. The absence of halogen bonds to all sites can be ascribed primarily due to deactivation of the σ-hole on the iodo-arene donors and partially due to steric hindrance. The tritopic acceptors containing 5,6-dimethylbenzimidazole derivatives yield discrete tetrameric aggregates in the solid state, whereas the pyrazole and imidazole analogues assemble into halogen-bonded 1-D chains.

Weak, Broken, but Working-Intramolecular Hydrogen Bond in 2,2'-bipyridine.

Project description:From an academic and practical point of view, it is desirable to be able to assess the possibility of the proton exchange of a given molecular system just by knowing the positions of the proton acceptor and the proton donor. This study addresses the difference between intramolecular hydrogen bonds in 2,2'-bipyridinium and 1,10-phenanthrolinium. Solid-state 15N NMR and model calculations show that these hydrogen bonds are weak; their energies are 25 kJ/mol and 15 kJ/mol, respectively. Neither these hydrogen bonds nor N-H stretches can be responsible for the fast reversible proton transfer observed for 2,2'-bipyridinium in a polar solvent down to 115 K. This process must have been caused by an external force, which was a fluctuating electric field present in the solution. However, these hydrogen bonds are the grain that tips the scales precisely because they are an integral part of a large system of interactions, including both intramolecular interactions and environmental influence.

The Halogen Bond.

Project description:The halogen bond occurs when there is evidence of a net attractive interaction between an electrophilic region associated with a halogen atom in a molecular entity and a nucleophilic region in another, or the same, molecular entity. In this fairly extensive review, after a brief history of the interaction, we will provide the reader with a snapshot of where the research on the halogen bond is now, and, perhaps, where it is going. The specific advantages brought up by a design based on the use of the halogen bond will be demonstrated in quite different fields spanning from material sciences to biomolecular recognition and drug design.

Ruthenium carboranyl complexes with 2,2'-bipyridine derivatives for potential bimodal therapy application.

Project description:Ruthenium complexes of carboranyl ligands offer the possibility of dual action (chemo + radiotherapy) that might result in significant clinical benefits. In that frame, we describe herein the development of ruthenium-carboranyl complexes bearing bipyridyl derivatives with the general formula [3-CO-3,3-{κ2-4,4'-R2-2,2'-bipy}-closo-3,1,2-RuC2B9H11] (R = CH3, RuCB1 or R = CH2OH, RuCB2). Both compounds crystallized in the monoclinic system, showing the expected three-legged piano stool structure. The ruthenacarboranes are stable in cell culture media and were tested against two cell lines that have shown favorable clinical responses with BNCT, namely melanoma (A375) and glioblastoma (U87). RuCB1 shows no cytotoxic activity up to 100 μM while RuCB2 showed moderate activity for both cell lines. Cell distribution assays showed that RuCB2 presents high boron internalization that is proportional to the concentration used indicating that RuCB2 presents features to be further studied as a potential anticancer bimodal agent (chemo + radiotherapy).

Tunable chiral triazole-based halogen bond donors: assessment of donor strength in solution with nitrogen-containing acceptors.

Project description:Strong halogen bond (XB) donors are needed for the activation of neutral substrates. We demonstrate that XB donor properties of iodo-triazoles can be significantly enhanced by quaternization in combination with varying the counterion and aromatic substituent, exemplified by association constants with quinuclidine as high as 1.1 × 104 M-1.

μ-Oxalato-bis-[bis-(2,2'-bipyridine)-manganese(II)] bis(perchlorate) 2,2'-bipyridine solvate.

Project description:The unit cell of the title compound, [Mn(2)(C(2)O(4))(C(10)H(8)N(2))(4)](ClO(4))(2)·C(10)H(8)N(2), consists of a binuclear cation, two perchlor-ate anions, and one solvent 2,2'-bipyridine (bpy) mol-ecule. In the complex cation [Mn(2)(C(2)O(4))(C(10)N(2)H(8))(4)](2+), two Mn(II) atoms are bridged by a bis-(bidentate) oxalate ligand, each Mn(II) atom being further coordinated by two bpy ligands in a distorted octa-hedral geometry. The distance between the two six-coordinated metal atoms is 5.583 (1) Å. π-π stacking inter-actions [inter-planar distances between bpy rings = 3.739 (1) Å] are essential to the supramolecular assembly. There are extensive inter-ionic C-H⋯O inter-actions between the cations and between the cation and anion. Three of the four perchlorate O atoms are disordered over two sets of sites with occupancy ratios of 0.852 (6):0.148 (6).

Bis(2,2'-bipyridine)(5,5'-imino-ditetra-zolato)cadmium(II) 2,2'-bipyridine hemisolvate monohydrate.

Project description:The title complex, [Cd(C(2)HN(9))(C(10)H(8)N(2))(2)]·0.5C(10)H(8)N(2)·H(2)O, was prepared under hydro-thermal reaction conditions. The asymmetric unit contains the cadmium complex, half a 2,2'-bipyridine solvent mol-ecule and a solvent water mol-ecule. The Cd(II) ion is coordinated by four N atoms from two 2,2'-bipyridine ligands and two N atoms from an HBTA(-) anion ligand [where H(2)BTA is N,N-bis-(1H-tetra-zol-5-yl)amine], forming an octa-hedral geometry. The complex is linked into a three-dimensional network by O-H⋯N and N-H⋯N hydrogen bonds and by the stacking inter-actions of rings, with distances of 3.5-3.7 Å between the atoms of two parallel 2,2'-bipyridine rings.

5,5'-Dimethyl-2,2'-bipyridine.

Project description:The asymmetric unit of the title compound, C(12)H(12)N(2), contains two half-mol-ecules related by an inversion center, the planes of their pyridine rings being oriented at a dihedral angle of 69.62 (4)°. In the crystal structure, a π-π contact between the pyridine rings [centroid-centroid distance = 3.895 (3) Å] may stabilize the structure. A weak C-H⋯π inter-action is also found.
