Abstract

An unusual one-dimensional cyclic tetrameric metavanadate, [PPh4]2V4O11 (1), has been crystallised from aqueous vanadate solution in the presence of tetraphenylphosphonium cations. Attempts to crystallise a tetraphenylarsonium analogue under identical conditions resulted in another new hybrid solid, [AsPh4]2(morph)4V10O28·2H2O (morph = morpholinium) (2). The single crystal structure reveals that 1 is an unprecedented example of a one-dimensional chain formed by a cyclic tetrameric vanadate while 2 contains decavanadate clusters and counter cations linked through hydrogen bonding to form an extended network.
