A new compound based on polyoxovanadate [{Ni(en)2}2Sb8V14O42]·5.5H2O(en=ethylenediamine)(1) was synthesised hydrothermally as black rhombus crystals.Compound 1 crystallized in the monoclinic system with space group P21/n,Z=4,a=1.46953(9) nm,b=1.28623(8) nm,c=1.76008(11) nm,β=105.7230(10)°.In the asymmetric unit,cluster {Sb8V14O42} can be considered as an Sb derivative of the {V18O42} unit.Each {Sb8V14O42} cluster as a building block interconnected to four other neighboring units by {Ni(en)2} bridging groups which are linked through the terminal oxygen atoms of the polyoxoanions,forming a two dimensional network.
