Abstract

Abstract Mr=1923.1, tetragonal, I4/mmm, a=11.366(2), c=19.638(6)Å, V=2537(1) Å3, Z=2,Dx=2.52 g cm−3, MoKα, λ =0.71069 Å, μ =3.12 mm−1, F(000)=1882, R=0.097 for 566 independent reflections. The crystal of K7[MnV13O38]·18H2O was found to be isomorphous to that of K7[NiV13O38]·18H2O. Corresponding interatomic distances between the two anions are essentially equal to each other. V–O bond distances range from 1.59 to 2.38 Å. One of the three K+ ions is tightly surrounded by 6–8 O atoms of the polyanions.
