A theoretical study on the strong codimer of C-60 and Si-60, C58Si58

Türker, Burhan Lemi
The strong codimer Of C-60 and Si-60 that is C58Si58 is considered for AM1 type semiempirical molecular orbital treatment at the, restricted Hartree-Fock level. The results reveal that C58Si58 structure should be highly endothermic but a stable molecule. The structure is expected to have some nonlinear properties.

Theoretical aspects of Si-60 structure having endohedral beryllium species, Be and Be+2
Türker, Burhan Lemi (2001-07-30)
Endohedrally Be and Be+2 doped Si-60 structures, Be@Si-60 and Be+2C@Si-60 are considered for AM1 type semiempirical molecular orbital treatment at the restricted Hartree-Fock level. The highly endothermic but stable structures are expected as the result of the calculations. Some donor-acceptor type electronic interaction between the dopants, Be and Be+2, and Si-60 cage occurs, causing some geometry distortions leading to high dipole moments as well as affecting the molecular orbitals
The effect of para-cyclophane structure on cyclacenes
Türker, Burhan Lemi (2000-02-01)
Semiempirical molecular orbital treatment at the level of AMI type has been performed on the Huckel type cyclacenes having the normal and the skew type para-cyclophane moiety embedded into their structures. The cyclophane effect is found to be operative on the lower members by veiling the cryptoannulenic effect which is influential on the heats of formation values and the frontier molecular orbital energies of the higher members as well as the parent cyclacenes.
A theoretical study on certain C-58 species
Türker, Burhan Lemi (2001-08-27)
Various electronic states of C-58 structure which is theoretically obtained from C-60 molecule by removing a C-2 unit and deleting a C-C bond shared by two adjacent hexagons have been considered for AM1 (UHF) type semiempirical molecular orbital calculations.
Some properties of cyclacenes and silacyclacenes
Türker, Burhan Lemi; Celebi, N (1997-04-01)
Various Huckel type cyclacenes and silacyclacenes are subject to semi-empirical molecular orbital treatment at the level of AMI type. Cyclacenes having silicon atom at the peri and fusion points of arenoid rings as well as all-silated cyclacenes are considered. The cryptoannulenic effects, frontier molecular orbital energies, geometries and polarizabilities of these structures have been examined.
A theoretical study of the cycloaddition between cyclopentadiene and allylideneammonium cation: An AM1 study
Zora, Metin (2002-12-09)
The Diels-Alder reaction between cyclopentadiene and allylideneammonium cation has been studied by means of AMI semiempirical method. Allylideneammonium cation can add to cyclopentadiene via its either C=C or C=N bond. For each cycloaddition, four reactive channels have been characterized corresponding to the endo-s-trans, endo-s-cis, exo-s-trans and exo-s-cis approach modes. The results indicate that C=C bond of allylideneammonium cation is more reactive as dienophile than its C=N bond in reaction with cyc...
