Vanadium Oxide Clusters as Building Blocks for the Synthesis of Metal Oxide Surfaces and Framework Materials: Synthesis and X-ray Crystal Structure of [H6Mn3VIV15VV4O46(H2O)12]·30H2O

A novel mixed-metal oxide solid [H6Mn3VIV15VV4O46(H2O)12]·30H2O (1) has been synthesized and characterized. The structure of the mixed-valence compound consists of three-dimensional arrays of “spheres” of {V19O46}, each one linked by six μ2-{Mn(H2O)4} bridges to six neighboring {V19O46} units, generating a complex 3-D framework. The structure contains cavities occupied by readily removable lattice water.
