N lone-pair···π interaction: a rotational study of chlorotrifluoroethylene···ammonia.
نویسندگان
چکیده
The rotational spectra of four isotopologues of the adduct C2F3Cl-NH3 show that NH3 is bound to the partner molecule through a (N)lone-pair···π interaction. Ammonia is located in proximity to the C2 atom (the one linked to two fluorine atoms), with the C2···N distance = 2.987(2) Å. The nuclear hyperfine structure due to the quadrupole coupling effects of (35)Cl/(37)Cl and (14)N nuclei has been fully resolved. The (14)N quadrupole coupling constants allow estimating the effective orientation of NH3 in the complex.

The impact of lone pair-π interactions on photochromic properties in 1-D naphthalene diimide coordination networks.
Lone pair-π interaction is an important but less studied binding force. Generally, it is too weak to influence the physical properties of supramolecular systems. Herein we reported the first example exhibiting the impact of lone pair-π interactions on photochromic properties of naphthalene diimide based coordination networks. In three isostructural 1-D networks, [(DPNDI)ZnX2] (DPNDI = N,N-di(4-...
متن کاملThe Main-Chain Oxygen: Unappreciated Effects on Peptide and Protein Structure
Current limitations in protein structure prediction and design suggest an incomplete understanding of the forces governing protein folding. As such, noncovalent interactions in proteins, particularly hydrogen bonds, have received great attention [1,2]. In common secondary structure patterns like the α-helix and β-sheet, main-chain N–H hydrogen bond donors approach their carbonyl acceptors appro...
متن کاملOn the non-classical contribution in lone-pair-π interaction: IQA perspective.
In the present work the nature of lone-pair-π interactions between water molecules and a number of π-rings with different substituents/hetero-atoms in the light of quantum chemical topology approaches is studied. The Quantum Theory of Atoms in Molecules (QTAIM) and Interacting Quantum Atoms (IQA) were employed for distinguishing the role of heteroatoms and electron withdrawing substituents in t...
متن کاملLone pair-π interaction-induced generation of non-interpenetrated and photochromic cuboid 3-D naphthalene diimide coordination networks.
Interpenetration is an intrinsic behaviour for the porous coordination networks. To prevent the interpenetration, a common strategy is the imposition of geometric or steric restrictions by incorporating bulky moieties into organic tectons. So far, most of the available incorporations have been achieved through a covalent connection, while few involved in the non-covalent weak interactions. In t...
متن کاملMolecular electrostatics for probing lone pair-π interactions.
An electrostatics-based approach has been proposed for probing the weak interactions between lone pair containing molecules and π deficient molecular systems. For electron-rich molecules, the negative minima in molecular electrostatic potential (MESP) topography give the location of electron localization and the MESP value at the minimum (Vmin) quantifies the electron-rich character of that reg...
