The first argentate salt of carborane anion, [{(CH 3 CN) 4 Ag 3 }{Ag(CB 11 I 5 Br 6 ) 2 }] n , was prepared from K 2 [CB 11 I 5 Br 6 ] and AgNO 3 followed by recrystallization from acetonitrile. Single‐crystal X‐ray analyses indicate that the CB 11 I 5 Br 6 2− dianion has a significantly different coordination motif from that of the CB 11 Br 5 I 6 − monoanion. This result suggests that the polarity of the CB 11 cage can be changed after deprotonation of the cage CH proton. Copyright © 2003 John Wiley & Sons, Ltd.
