Synthese und Kristallstruktur von NaMgl,64Cu0,36V3O10/ Synthesis and Crystal Structure of NaMgl,64Cu0,36V3O10

Abstract

Abstract Single crystals of NaMg1.64Cu0.36V3O10 have been prepared by heating mixtures of Na2CO3, MgCO3, CuO and V2O5 above the melting point. The yellow crystals show triclinic symmetry, space group Ci 1-P1̅, a = 6.726(8), b = 6.743(7), c = 9.625(2) Å, α = 100.705(9), β = 104.57(1), γ = 101.700(9)°, Z = 2. NaMg1.64Cu0.36V3O10 represents a new structure type showing V3O10 groups, a statistical distribution of Mg2+ and Cu2+ on two point positions, and Na+ in an irregular coordination.
