Synthesis and crystal structures of [H3N(CH2)(2)NH3]NbMOF(PO4)(2)(H2O)(2), M = Fe,Co and [H3N(CH2)(2)NH3]Ti(Fe0.9Cr0.1)(F1.3O0.7)(H0.3PO4)(2)(H2O)(2)

摘要

The new niobium phosphates [H3N(CH2)(2)NH3]NbFeOF(PO4)(2)(H2O)(2) and [H3N(CH2)(2)NH3]NbCoOF(PO4)(2)(H2O)(2) have been synthesized in single crystal form by hydrothermal reactions at 165 degrees C. The new phase [H3N(CH2)(2)NH3]Ti(Fe0.9Cr0.1)(F1.3O0.7)(H0.3PO4)(2)(H2O)(2) has been obtained by hydrothermal electrocrystallization at 170 degrees C. The crystal structures have been refined from X-ray diffraction data. They are structurally similar to the known layered iron phosphate [H3N(CH2)(2)NH2][Fe2F2(HPO4)(2)(H2O)(2)] designated as ULM-10 and the mineral curetonite. [References: 24]
