Abstract: Three novel hetero-polyoxovanadates, [Cd(2,2′-bpy)3]{[Cd(dien)]As8V14O42(H2O)} (1, 2,2′-bpy=2,2′-bipyridine, and dien=diethylenetriamine), [Zn(2,2′-bpy)2]2[As8V14O42(H2O)]·H2O (2) and [Ni(en)2]3[As8V14O42(HPO3)]·4H2O (3, en=ethlenediamine), were hydrothermally synthesized and characterized by single-crystal X-ray diffraction. Crystal data: 1 monoclinic, P2(1)/n, , , , , Z=4. 2, orthorhombic, P2(1)2(1)2(1), , , , . 3, triclinic, , , , , , , , . Compounds 1–3 are all made of the {As8V14O42} shells linked by corresponding transition metal complexes into extended structures. Compound 1 and 2 present 1-D wave-like and tubular structures, respectively, while compound 3 exhibits a novel 2-D structure containing interwinding puckery layers. Variable temperature susceptibility measurements demonstrate the presence of antiferromagnetic interaction between VIV cations in 1 and 2. [Copyright &y& Elsevier]
