Abstract:

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.
