The title compound [Co(en)2(H2O)]{[Co(en)2]2As8V14O42(SO4)} · 3H2O (1) (en = ethylenediamine) has been hydrothermally synthesized and characterized by single crystal X-ray diffraction, IR spectrum and thermogravimetric analysis. The single crystal diffraction analysis shows that compound 1 exhibits {[Co(en)2]2As8V14O42(SO4)}n2n− layers act as ligand of coordination cations [Co(en)2]2+, and water molecules are inserted in the layers. The magnetic measurement indicates a weak antiferromagnetic exchange coupling within the molecular unit, which is deemed to attribute to the contribution of Viv and Co2+.
