Abstract: During crystallization of MgB4O7·9H2O,NaB5O8·5H2O,MgB6O10·7H2O and MgB6O10·7.5H2O,the structures of their mother liq uors have been studied by differential FT-IR spectra.There exist characteristic frequen cies of polyborate anions in zone of 800~1000cm-1 .The recorded frequencies of the borate aqueous so lutions were assigned.The peaks of 870,810cm-1 were char-acteristic of triborate anion,and t hose of 844,929 and 959cm-1 were characteristic of tetra-,penta-and hexa-borate,respectively.
