INVESTIGATIONS INTO THE TARGETED DESIGN OF SOLIDS - HYDROTHERMAL SYNTHESIS AND STRUCTURES OF ONE-DIMENSIONAL, 2-DIMENSIONAL, AND 3-DIMENSIONAL PHASES OF THE OXOVANADIUM-ORGANODIPHOSPHONATE SYSTEM

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 32− 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. (Figure Presented.) Copyright © 1995 by VCH Verlagsgesellschaft mbH, Germany
