| 中文摘要 | the ir spectrum and b-11 and al-27 mas nmr spectra of al18b4o33 are presented and discussed in relation to the possible existence of boron atoms substituting for aluminum atoms. the ir spectrum shows that the strong vibrations of the bo3 groups are present in the 1 500 similar to1 200 cm(-1) region, and very weak bands of bo4 units art present in the region from 1 000 to 1 100 cm(-1). b-11 mas nmr spectrum indicates that the strong signal for bob units appears in the region from delta +5 to delta +20, and the very weak signal for bo4 units is at about delta -1, while al-27 mas nmr spectrum shows five peaks at about delta +62, +42.1, +14, -4.7 and -6.4, originating from alo4, alo4, alo5, alo6 and alo6, respectively, these results reveal that there are minor bo4 units in al18b4o33, indicating that a small amount of b atoms substitute for al atoms in the 4-fold coordination. |
