Two new polyoxometalates [Ni(phen){sub 3}][Ni(en){sub 3}][Ni(en){sub 2}(H{sub 2}O){sub 2}][Ni(en){sub 2}]{sub 0.5}[PW{sup VI}{sub 7}W{sup V}{sub 2}V{sup IV}{sub 3}O{sub 40}(V{sup IV}O) {sub 2}].6H{sub 2}O (1) and [Ni(phen){sub 3}]{sub 2}[Ni(en){sub 2}]Na[PW{sup VI}{sub 7}W{sup V}{sub 2}V{sup IV}{sub 3}O{sub 40}(V{sup IV}O){sub 2}].8H{sub 2}O (2) (en=ethylenediamine, phen=1,10-phenanthroline) have been hydrothermally synthesized and structurally characterized by single-crystal X-ray diffraction, IR, EPR, XPS, elemental analysis and thermogravimetry. Their structures exhibit interesting 3D supramolecular networks, and contain new bicapped (pseudo-) Keggin-type tungsten-vanadium cluster and the template transition-metal complexes (TMCs) being generated in situ under mild hydrothermal conditions. Interestingly, compound 1 contains four different kinds of nickel complex countercations. - Graphical abstract: The structures of [Ni(phen){sub 3}][Ni(en){sub 3}][Ni(en){sub 2}(H{sub 2}O){sub 2}][Ni(en){sub 2}]{sub 0.5}[PW{sup VI}{sub 7}W{sup V}{sub 2}V{sup IV}{sub 3}O{sub 40} (V{sup IV}O){sub 2}].6H{sub 2}O (1) and [Ni(phen){sub 3}]{sub 2}[Ni(en){sub 2}]Na[PW{sup VI}{sub 7}W{sup V}{sub 2}V{sup IV}{sub 3}O{sub 40}(V{sup IV}O){sub 2}].8H{sub 2}O (2) exhibit interesting 3D supramolecular networks constructed by bicapped Keggin heteropolyanions and the in situ templates transition metal complexes.
