Comparison of halogen bonding and van der Waals and π-π Inter-actions in 4,5-dibromo-2-hexyl-oxyphenol
(Wiley Blackwell Publishing, Inc, 2009-04)
The title compound, C12H16BrO2, is an inter-esting case of a simple organic mol-ecule making use of five different types of intra- and inter-molecular inter-actions (viz. conventional and nonconventional hydrogen bonds, ...
N-H...Br, Br...π and π...π interactions toward self-assembly of the cytosine hydrobromide: crystal structure, infrared spectroscopy and thermal behavior
(Elsevier BVAmsterdam, 2013-09)
The cytosine hydrobromide (CytHBr) was obtained and studied by single-crystal X-ray diffraction, FT-IR spectroscopy and thermal analysis. This salt crystallizes in the P'2IND.1/n space group with one ionic-pair CytH+Br in ...
Halogen...halogen contacts for the stabilization of a new polymorph of 9,10-dichloroanthracene
(Elsevier BVAmsterdam, 2014-02)
A new polymorph of 9,10-dichloroanthracene (9,10-DCA) namely as 'gama' form, was obtained. The crystal structure of the 'gama' polymorphic system showed an orthorhombic P212121 space group with a = 3.8957(2) Å, b = 15.9383(5) ...
The three-component cocrystal 1,3,5-trifluoro-2,4,6-triiodobenzene-pyridine N-oxide-water (1/2/1) built up by halogen bonds, hydrogen bonds and π-π interactions
(International Union of Crystallography, 2015-02)
The title three-component cocrystal, C6F3I3·2C5H5NO·H2O, has been prepared as a strong candidate for multiple I⋯O interactions. Its crystal structure is compared with its 1:1 close relative, C6F3I3·C5H5NO [Aakeröy et al. ...
Polymorphism of a widely used building block for halogen-bonded assemblies: 1,3,5-Trifluoro-2,4,6-Triiodobenzene
(International Union of Crystallography, 2017-09)
After reporting the structure of a new polymorph of 1,3,5-Trifluoro-2,4,6-Triiodobenzene (denoted BzF3I3), C6F3I3, (I), which crystallized in the space group P21/c, we perform a comparative analysis with the already reported ...
Relative influence of noncovalent interactions on the melting points of a homologous series of 1,2-dibromo- 4,5-dialkoxybenzenes
(Wiley Blackwell Publishing, Inc, 2013-01)
Crystal structures are presented for two members of the homologous series of 1,2-dibromo-4,5-dialkoxybenzenes, viz. those with decyloxy and hexadecyloxy substituents, namely 1,2-dibromo-4,5-bis(decyloxy)benzene, C26H44Br2O2, ...
Halogen⋯halogen contacts for the stabilization of a new polymorph of 9,10-dichloroanthracene
(Elsevier Science, 2014-02)
A new polymorph of 9,10-dichloroanthracene (9,10-DCA) namely as γ form, was obtained. The crystal structure of the γ polymorphic system showed an orthorhombic P212121 space group with a = 3.8957(2) Å, b = 15.9383(5) Å, c ...
Influence of methoxy-substituents on the strength of Br ... Br type II halogen bonds in bromobenzoic acid
(Elsevier Science, 2016-03)
4-bromo-3,5-di(methoxy)benzoic acid (I) crystallizes in the monoclinic C2/c space group, a = 22.3405 (6) Å, b = 4.85142 (14) Å, c = 18.1583 (5) Å, β = 93.086 (2)°. The crystal structure shows head-to-head dimeric units ...
