Hydrothermal synthesis and structure of a three-dimensional trimetallic oxide, Na2[CuV2O2(H2O)2(O3PCH2PO3)2]

The hydrothermal chemistry of the oxovanadium/methylphosphonate/copper(II) system has been investigated. The structure of the trimetallic hybrid oxide, Na2Cu[V2O2(H2O)2(O3PCH2PO3)2] (1), is shown.
