Crystal structure of octakis(N,N-dimethylformamide-κO)europium(III) tetracosa-μ2-oxido-dodecaoxido-μ12-phosphato-dodecamolybdate(VI)

Abstract

In the title salt, [Eu(C3H7NO)8][PMo12O40], the asymmetric unit comprises one α-Keggin-type [PMo12O40]3−polyoxidometalate anion and one distorted dodecahedral [Eu(C3H7NO)8]3+complex cation. In the crystal, the isolated polyoxidometalate anions are packed into hexagonally arranged rows extending parallel to [001]. The complex cations are situated between the rows and are linked to the neighbouring anions through weak C—H...O hydrogen-bonding interactions, leading to the formation of a three-dimensional network structure.
