Chromium bisanthracene-(6) complexes are considered within the framework of density functional theory using LANL2DZ and 6-31+G(d) basis sets and B3LYP functional. The complexation with both the same types of rings of anthracene decks (AA- and BB-type complexes) and with different rings (AB-type complex) are considered. The optimized geometries and the associated quantum chemical properties are comparatively discussed for the both types of basis sets used. LANL2DZ basis set yielded some unreasonable results. B3LYP/6-31+G(d) level of calculations yielded the stability order as AA > BB > AB. IR spectra of AA and BB-type complexes resemble each other. The C-H frequencies are almost the same for both of the anthracene decks, whereas they differ in the case of AB-type complex. UV/Vis spectra of the complexes all absorb above 500 nm. AA and AB-type complexes in contrast to BB-type display rather complex pattern. The NICS(0) values of various rings in the complexes considered are obtained and discussed.

Nitro Derivatives of Parabanic Acid as Potential Explosives: A Theoretical Study
Türker, Burhan Lemi; Varis, Serhat (2014-01-01)
This work deals with certain parabanic acid (PA) derivatives because they possess great calculated density (>1.8 gcm(-3)) and high content of nitrogen (26%). Computed ballistic properties of eight different parabanic acid derivatives are presented. The structures were optimized at the B3LYP/6-31G(d, p) level. The calculated data for PA are found to be compatible with the experimental X-ray data. The detonation performance analyses were done using empirical Kamlet-Jacobs equations. Additionally, detonation p...
Molecular structure and vibrational spectra of 4-tert-butylpyridine by density functional theory and ab initio Hartree-Fock calculations
Kurt, M; Yurdakul, Murat Hayrettin; Yurdakul, S (2003-11-28)
The molecular geometry and vibrational frequencies of 4-tert-butylpyridine(4-tbpy) in the ground state have been calculated by using the Hartree-Fock and density functional methods (B3LYP and BLYP) with 6-31G (d) as the basis set. The optimized geometric bond lengths obtained by using B3LYP and bond angles obtained by BLYP show the best agreement with the experimental values. Comparison of the observed fundamental vibrational frequencies of 4-tbpy and calculated results by density functional B3LYP, BLYP and...
Benzaldehyde lyase catalyzed enantioselective self and cross condensation reactions of acetaldehyde derivatives
Ayhan, Peruze; Turan, Ilke Simsek; Cifci, Burce; Demir, Ayhan Sıtkı (Royal Society of Chemistry (RSC), 2011-01-01)
Flexible protected 1,3,4-trihydroxy-2-butanone is synthesized in high enantiomeric excesses by using asymmetric homo- and cross- acyloin coupling of aliphatic aldehydes catalyzed by benzaldehyde lyase.
A van der Waals density functional investigation of carboranethiol self-assembled monolayers on Au(111)
Yılmaz, Ayşen; Danışman, Mehmet Fatih (2016-05-14)
Isolated and full monolayer adsorption of various carboranethiol (C2B10H12S) isomers on the gold(111) surface has been investigated using both the standard and van der Waals density functional theory calculations. The effect of different molecular dipole moment orientations on the low energy adlayer geometries, the binding characteristics and the electronic properties of the self-assembled monolayers of these isomers has been studied. Specifically, the binding energy and work function changes associated wit...
AM1 treatment of some C60H2 and Be@C60H2 systems
Türker, Burhan Lemi (2002-07-26)
Vicinally hydrogenated C-60 and endohedrally beryllium-doped vicinally hydrogenated C-60 structures are considered within the framework of AM1(SCF) type semiempirical calculations. The regioisomers and stereoisomers of the hydrogenated products are compared from thermodynamic point of view. Endohedrally beryllium-atom doping has been found stable for C60H2 systems having hydrogens inside the cage.
