Hydrothermal synthesis, characterization and magnetic properties of NaVGe2O6 and LiVGe2O6
Supercritical fluids are shown to be an excellent reaction media for the synthesis of novel solid state phases at intermediate temperatures. LiVGe 2O6 and NaVGe2O6 have the common pyroxene structure composed of VO6 linear ...
Hydrothermal synthesis and characterization of one dimensional chain structures of monolacunary Keggin polyoxoanions substituted with copper
Two novel polymeric polyoxometallates constructed from transition metal substituted heteropolytungstates, [(4,4’bpyH2)2(4,4’bpyH)][PCuW11O39]·H2O (1), and [(4,4’bpyH2)(pyH)3][PCuW11O39]·2H2O (2), (4,4’bpy = 4,4’bipyridine, ...
Hydrothermal synthesis and characterization of a new layered compound Li2VGeO5
The new compound Li2VGeO5 with a layered structure has been synthesized at 580°C via the hydrothermal method. The compound crystallizes in the space group P4/n of the tetragonal system with two formula units in a cell of ...
