In the title compound, [Cu(C16H19BrNO4)(2)]center dot 2H(2)O, the Cu-II ion resides on an inversion centre and is coordinated by two O and two N atoms from two enantiomeric 5-(4-bromophenyl)-4-(tert-butoxycarbonyl)pyrrolidine-2-carboxylate ligands in a distorted square-planar geometry. The relative stereochemistry of the three stereogenic C atoms in each ligand has been determined. In the crystal, intermolecular N-H center dot center dot center dot O and O-H center dot center dot center dot O hydrogen bonds link the molecules into layers parallel to the bc plane. The crystal studied was twinned by pseudomerohedry with twin fractions of 0.719 (3) and 0.281 (3).

In the title compound, C(21)H(21)N(3)O(3), the relative stereochemistry of the four stereogenic C atoms has been determined. The dihedral angle between the phenyl rings is 77.63 (7)degrees. In the crystal, ribbons spread along the a axis are formed by N-H center dot center dot center dot O hydrogen bonds. C-H center dot center dot center dot pi interactions also occur.
Zero-n gap design via modulation of hexagonal photonic crystal lattice
Moradi, Shahram; Kocaman, Serdar; Yüce, Emre; Department of Micro and Nanotechnology (2017)
We study the effect of disorder in the lattice on a photonic band diagram and apply it to form a superlattice in order to examine negative refractive index and finally obtain zero-ñ gap. In addition, the novelty of suggested modulated PhC introduces new ways of controlling light through the complicated lattices. The aim of this approach is to have a deep understanding of dispersion characteristics dependence on the lattice structure by comparing modified structures with conventional lattice types. We design...
Optical constants and interband transitions of anisotropic layered structured Tl2GaInS4 crystals by spectroscopic ellipsometry
IŞIK, MEHMET; Hasanlı, Nızamı; Turan, Raşit (2013-02-05)
Spectroscopic ellipsometry measurements were carried out on Tl2GaInS4 layered crystals for orientations of electric field vector, parallel (E//c*) and perpendicular (E perpendicular to c*) to optical axis c*. The measurements were performed in the 1.2-6.2 eV spectral range at room temperature. The real and imaginary components of the pseudodielectric function, pseudorefractive index and pseudoextinction coefficient were calculated from the analysis of ellipsometric data. The energies of interband transition...

The structure of the title compound, C8H12O2, which is a rearrangement product of the reaction of 6-hydroxy-4,4-dimethylcyclohex-2-en-1-one and 4-dimethylaminopyridine has been identified as 2-hydroxy-5,5-dimethylcyclohex-2-en-1-one, The C atom of the six-membered ring connected to the two methyl groups is 0.617(2)Angstrom out of the least-squares plane defined by the other C atoms of the rin. The unit cell consists of discrete molecules with intra-and intermolecular hydrogen bonds.
Functional Group Effects on the Electrochemical Properties of Carboranethiol Monolayers on Au(111) As Studied by Density Functional Theory: Implications for Organic Electronics
Yortanli, Merve; Danışman, Mehmet Fatih; Mete, Ersen (2022-08-01)
Positional isomers of dicarba-doso-dodecaboranethiols with various functional groups (-NO2, -CHO, -CONH2, -F, -Cl, and -OH) were considered on Au(111) forming (3 x 3) and (5 x 5) structures. Dispersion corrected density functional theory calculations reveal the influence of functional groups on the adsorption characteristics of these carboranethiols depending on the coverage. Functionalized molecules not only possess fascinating chemical and electronic properties but also show stronger chemisorption profile...
