The new heteropolyoxometalate compound (C6H8N)5[HAs2Mo6O26(H2O)]3H2O: crystal structure and Hirshfeld surface analysis

A detailed description of the crystal structure and a Hirshfeld surface analysis of the new heteropolyoxometalate compound (C6H8N)5[HAs2Mo6O26(H2O)]- 3H2O are reported. The title compound was synthesized using solution methods and its structure was characterized by single-crystal X-ray diffraction. The investigated compound contains a new [HAs2Mo6O26(H2O)]5 polyanion and crystallizes in the monoclinic space group P21/c. The crystallographic analysis provided an understanding of the architecture and structural features of the complex crystal lattice and the Hirshfeld surface analysis shed more light on the intermolecular interactions occurring in the crystal.
