Abstract

The new compound Ag2Mn3(VO4)3 was synthesized by hydrothermal and solid state reaction routes, and its crystal structure was determined from single-crystal X-ray diffraction data. Ag2Mn3(VO4)3 crystallizes with a monoclinic symmetry, space group C2/c, with a=11.8968(11) Å, b=13.2057(13) Å, c=6.8132(7) Å, β=111.3166(15) (°) and V=997.16(17) Å3 (Z=4). Its crystal refinement yielded the residual factors R(F)=0.0249 and wR(F2)=0.0704 for 95 parameters and 1029 independent reflections at a 3σ(I) level. Ag2Mn3(VO4)3 can be considered as a new member of the AA′MM′2(XO4)3 alluaudite family. The specific arrangement of M and M′ octahedral sites and of X tetrahedral sites gives rise to two different channels aligned along the crystallographic c-axis and containing the A and A′ sites. The A, A′, M, and X sites are fully occupied by Ag+, Mn2+, and V5+, respectively; whereas a Mn2+/Mn3+ mixture is observed in the M′ site.
