Investigations into the Targeted Design of Solids: Hydrothermal Synthesis and Structures of One‐, Two‐, and Three‐Dimensional Phases of the Oxovanadium–Organodiphosphonate System

Abstract

Depending on the tether length of the diphosphonate group, hydrothermal reactions of VCl4 with diphosphonic acids of the class (H2O3P)(CH2)n(PO3H2) in the presence of templating organic cations yield one-, two-, and three-dimensional framework structures of the V-O-RPO system. The picture shows a section of the three-dimensional framework of [H3N(CH2)2NH3][(VO)4(OH)2(H2O)2{O3P(CH2)3PO3}2]·4H2O.
