АннотацияЖурнал физико-химического профиля. Адресован специалистам, работающим в области квантовой химии, физических методов исследования, кристаллохимии, супрамолекулярной химии, структуры и свойств наноматериалов, строения жидкостей, а также широкому кругу химиков. Своеобразие журнала заключается в том, что для исследования электронного и пространственного строения химических соединений в публикуемых работах широко применяются современные физические методы, оригинальные теоретические и экспериментальные подходы. Форма публикаций - статьи, краткие сообщения, тематические обзоры по различным проблемам структурной химии. С 2004 г. Издаётся ежегодное Приложение к Журналу, в котором публикуются статьи по актуальным направлениям структурной химии. Журнал переводится на английский язык, издается и распространяется за рубежом Издательством Springer. Название англоязычного издания Journal of Structural Chemistry.

Li2*, Y. Zhang1, S. Zhao1 1 Department of Anesthesiology, Affiliated N 4 Hospital of Soochow University, Wuxi, Jiangsu 214062, P.R. China 2 Department of Chemistry and Chemical Engineering, Weinan Teachers University, Weinan, Shaanxi 714000, P.R. China Received December, 28, 2008 A series of exohedrally functionalized derivatives of the D6-symmetrical C24 fullerene, with attached CH2OH, CONH2, COOH, and COH chemical groups, have been investigated by using density-functional theory approach at the UB3LYP/6-31G(d) level. <...> According to the calculated results, the C24(COOH) is the most stable structure, with 73.58 kcal mol1 value for the functionalization reaction energy and 3.16 eV for the dissociation energy, while C24(CONH2) displays the largest dipole moment (3.09 D). <...> It was also found that the HOMO LUMO energy gaps, the vertical ionization potentials (VIP), and vertical electron affinities (VEA) of these functionalized derivatives are similar to those of the more stable C24 fullerene. <...> K e y w o r d s: C24 fullerene, derivative, structure, thermochemistry, DFT. <...> Optimized ground-state structure of the C24 molecule as viewed along the direction perpendicular to one of its hexagonal faces. <...> All bond distances are in Angstroms stability of C60(Glycine)n (where n = 14) has also been studied by means of AM1 calculations to determine the positions where glycine molecules are preferentially added onto [60]fullerene molecule [ 21 ]. <...> Four neutral chemical groups have been introduced as substituents in the C24 fullerene, namely (i) CH2OH, (ii) CONH2, (iii) COOH, and (iv) COH. <...> Based on the D6-symmetrical C24 fullerene, its derivatives, which have been exohedrally functionalized by attaching CH2OH, CONH2, COOH, and COH chemical groups, have been calculated at the UB3LYP/6-31G(d) level of theory. <...> Some properties have been investigated for the stable structures, including the optimized structures, vibrational frequencies, dipole moments, reaction <...>
