| Abstract: | The compound (enH2)3.5As8V14O42(PO4)]·2H2O 1 (en=ethylenediamine) has been synthesized and characterized by means of elemental analysis, IR spectrum, ESR spectrum, XPS spectrum, TG analysis and single crystal X-ray diffraction analysis. The compound 1 crystallizes in monoclinic system, space group C2/c,    β=105.59(3),  Z=8 and R1(wR2)=0.0398(0.0885). The compound 1 is constructed from As8V14O42(PO4)]7− anions and H2en cations linked through hydrogen bonds into a network. The As8V14O42(PO4)]7− cluster consists of 14 VO5 square pyramids linked by 4 As2O5 handle-like units, and includes at its center an ordered PO43− anion. |
