The title compound, C(30)H(18)Cl(6)O(3)·0.82CH(2)Cl(2), consists of a slightly cup-shaped seven-ring truxene nucleus with hy-droxy and dichloro-methyl substituents at stereocenters 5R/S, 10R/S and 15R/S. C-Cl distances are in the range 1.759 (4)-1.783 (3) Å. Solvent channels parallel to the b axis appear to be partially occupied by highly disordered dichloro-methane solvent mol-ecules, the cont...

The title compound, C35H28N4O6S, crystallizes with two mol-ecules in the asymmetric unit. In both mol-ecules, the piperidine ring adopts a shallow-chair conformation, the thia-zole ring adopts a twisted conformation about the Cm-N bond (m = methine) and the pyrrole ring adopts an envelope conformation with the C atom shared with the thia-zole ring as the flap. In the crystal, inversion dimers l...

In the title compound, C(11)H(11)NO(2), the mean planes formed by the benzene ring and the C and N atoms of the acryl group are almost orthogonal to each other, with a dihedral angle of 85.7 (1)°. During the structure analysis, it was observed that the unit cell contains large accessible voids, with a volume of 186.9 Å(3), which may host disordered solvent mol-ecules. This affects the diffracti...

In the title compound, C20H25NO5, the di-hydro-pyridine ring adopts a flattened boat conformation. The meth-oxy-phenyl ring is almost perpendicular to the mean plane of the pyridine ring [dihedral angle = 88.42 (3)°]. The two carbonyl units adopt a synperiplanar conformation with respect to the double bonds in the di-hydro-pyridine ring. In the crystal, mol-ecules are connected by N-H⋯O hydroge...

Peer-reviewed journal articles (n=1068) were used to gather instrumental color measurement information in meat science research. The majority of articles, published in 10 peer-reviewed journals, originated from European countries (44.8%) and North America (38.5%). The predominant species was pork (44.2%), and most researchers used Minolta (60.0%) over Hunter (31.6%) colorimeters. Much of the re...

There are currently five transformation matrices being considered for use in the linear chromatic-adaptation transform in a revision of the CIECAM97s color appearance model. Four of the matrices were developed independently for the purpose of transforming tristimulus values to spectrally sharpened RGB responses. The fifth is the HuntPointer-Estevez transform of CIE tristimulus values to normali...

The mol-ecular structure of the title compound, C50H40N2Se2·C2H3N, shows a syn conformation of the benzene rings bound to the Se atoms, with an Se-Se bond length of 2.3529 (6) Å and a C-Se-Se-C torsion angle of 93.53 (14)°. The two Se-bonded aromatic ring planes make a dihedral angle of 18.42 (16)°. Intra-molecular N-H⋯Se hydrogen bonds are noted. Inter-molecular C-H⋯Se inter-actions give rise ...

In the title polymer, {[Co(C(14)H(10)N(2)O(4))(H(2)O)]·3.5H(2)O}(n), the Co(2+) ion is coordinated by three carboxyl-ate O atoms from two 5-[(pyridin-2-ylmeth-yl)amino]-isophthalate anions, two N atoms from a (pyridin-2-ylmeth-yl)amino group and an O atom from a water mol-ecule, furnishing a distorted CoO(4)N(2) octa-hedral geometry. Each anion acts as a μ(3)-bridge, linking cobalt ions into a ...

Characterization and estimation of device independent color co-ordinates of scanned or photographic images of through empirical models is a typical issue for commercial desktop scanners and cameras. As a domain of complex problem for optimising suitable color model to evaluate textiles and paints, we investigated the effect of different DPI and device independent color coordinate selection for ...
