THE MINIMAL SET OF INTERMOLECULAR INTERACTIONS IN THE STRUCTURES OF SUBSTITUTED PROLINES

open access: yesStudia Universitatis Babes-Bolyai Chemia, 2017
In this paper, the calculation of intermolecular interaction energy based on Gavezzotti–Filippini semi-empirical method was performed for the series of substituted prolines. The initial structural data were mined from Cambridge Structural Database.

Hydrogen-bonding interactions in the crystalline-phase structures of cinnamic acid derivatives [PDF]

open access: yes, 1999
Secondary interactions responsible for the crystalline-phase structures of various cinnamic acids and cinnamic acid esters drawn from the Cambridge Structural Database were studied with the help of the Cerius package implemented on an SGI workstation ...

π–π Noncovalent Interaction Involving 1,2,4- and 1,3,4-Oxadiazole Systems: The Combined Experimental, Theoretical, and Database Study

open access: yesMolecules, 2021
A series of N-pyridyl ureas bearing 1,2,4- (1a, 2a, and 3a) and 1,3,4-oxadiazole moiety (1b, 2b, 3b) was prepared and characterized by HRMS, 1H and 13C NMR spectroscopy, as well as X-ray diffraction.

The Phosphorus Bond, or the Phosphorus-Centered Pnictogen Bond: The Covalently Bound Phosphorus Atom in Molecular Entities and Crystals as a Pnictogen Bond Donor

open access: yesMolecules, 2022
The phosphorus bond in chemical systems, which is an inter- or intramolecular noncovalent interaction, occurs when there is evidence of a net attractive interaction between an electrophilic region associated with a covalently or coordinately bonded ...

Bond length of perchlorate at different temperatures: X-ray and neutron comparison. [PDF]

open access: yes, 2020
The averages (average deviations from the mean are given in square brackets) of uncorrected Cl-O bond distances in a perchlorate anion from an X-ray diffraction analysis of (N-{2-[bis(pyridin-2-ylmethyl)amino]ethyl}pyridine-2-carboxamidato)(nitric oxide ...

Use of software to search for higher symmetry: space group C2 [PDF]

open access: yes, 2001
From a search of the October 2000 release of the Cambridge Structural Database we find coordinate data for approximately 1500 entries under space group No. 5: C2 or, occasionally, A2, I2 or B112.

π-Hole Tetrel Bonds—Lewis Acid Properties of Metallylenes

open access: yesCrystals, 2022
The MP2/aug-cc-pVTZ calculations were performed on the dihalometallylenes to indicate their Lewis acid and Lewis base sites. The results of the Cambridge Structural Database search show corresponding and related crystal structures where the tetrel center

Structural study of the coordination behavior of a tetradentate NO3-donor amino alcohol ligand toward a CdII:HgII mixture [PDF]

open access: yes, 2017
In this work, the reaction of 2,2′,2″-nitrilotriethanol (NTE) with a 1:1 mixture of CdI2 and HgI2 is investigated. The complex [Cd(NTE)2][Hg2(μ-I)2I4] was synthesized and identified by elemental analysis, FT-IR, 1H NMR spectroscopy and single-crystal X ...

N,N′-Bis(4-bromophenyl)-N,N′-dimethylurea

open access: yesIUCrData, 2018
The structure of the title compound, C15H14Br2N2O, at 180 K has monoclinic (P21/n) symmetry. It was obtained unexpectedly from the decomposition of the parent 4-bromo-N-tert-butoxycarbonyl-N-methyl-aniline.
