Glass Formation in the Al2(SO4)3–(CH3)2SO–H2O System

The glass formation in the Al 2 (SO 4 ) 3 –(CH 3 ) 2 SO–H 2 O system was found for the first time. The competitive ability of ligands, dimethyl sulfoxide and water (which are strong donors), for entering the first coordination sphere of aluminum is considered. The possibility of mixed coordination of (CH 3 ) 2 SO (via sulfur and oxygen atoms) in the first coordination sphere of aluminum with retention of the glass-forming ability of the sample was suggested on the basis of IR spectral study.
