中文摘要 | bond distances, vibrational frequencies, electron affinities, ionization potentials, dissociation energies, and dipole moments of the title molecules in neutral, positively, and negatively charged ions were studied using the density functional method. ground state was assigned for each species. the bonding patterns were analyzed and compared with both the available data and across the series. it was found that besides an ionic component, covalent bonds are formed between the metal s, d orbitals and the silicon 3p orbital. the covalent character increases from scsi (ysi) to nisi (pdsi) for 3d (4d) metal monosilicides, then decreases. for 5d metal monosilicides, the covalent character increases from lasi to ossi, then decreases. for the dissociation of cations, the dissociation channel depends on the magnitude of the ionization potential between metal and silicon. if the ionization potential of the metal is smaller than that of silicon, channel msi+-> m++si is favored. otherwise, msi+-> m+si+ will be favored. a similar behavior was observed for anions, in which the dissociation channel depends on the magnitude of electron affinity. |
