description

Abstract An unified synthetic approach has allowed us to isolate a wide set of highly condensed oxoanionic derivatives of transition metals by using solution chemistry procedures. New phases are described [Ni 12+ x H 6−2 x (AsO 4 ) 8 (OH) 6 . Ni 6 (SeO 3 ) 4 (OH) 4 ], and the preparation of other already known [Ni 12+ x H 6−2 x (PO 4 ) 8 (OH) 6 , Ni 3 Te 2 O 6 (OH) 2 ] is significantly simplifi ed. The structure of these derivatives, as well as that of other phases such as M 11 (HPO 3 ) 8 (OH) 6 (M=Zn, Co, Ni), previously characterized by us, can be related to that of the dumortierite mineral. The main features of the tubular channels that characterize this structure and the possibility to modulate their chemistry are discussed on the basis of the nature of both cationic and anionic components.
