Three heterometallic 1-D polymers, [{l_brace}Ni(1,10-phen){sub 2}(H{sub 2}O){r_brace}{sub 2} {l_brace}(Mo{sub 5}O{sub 15})(4,4'-dbp){r_brace}.(5.75H{sub 2}O)] (4,4'-dbp=O{sub 3}PCH{sub 2}C{sub 6}H{sub 4}C{sub 6}H{sub 4}CH{sub 2}PO{sub 3}) (1), [{l_brace}Co(1,10-phen){sub 2}(H{sub 2}O){r_brace}{sub 2} {l_brace}(Mo{sub 5}O{sub 15})(4,4'-dbp){r_brace}.(5.5H{sub 2}O)] (2) and [{l_brace}Ni(2,2'-bpy){sub 3}{r_brace}{l_brace}Ni(2,2'-bpy){sub 2}(H{sub 2}O){r_brace} {l_brace}(Mo{sub 5}O{sub 15})(4,4'-dbp){r_brace}.(4.75H{sub 2}O)] (3), have been synthesized under hydrothermal conditions. Their structures were determined by single crystal X-ray diffraction. The 1-D chains is constructed of [Mo{sub 5}O{sub 15}(4,4'-dbp)]{sup 4-} units, which are further decorated and charge compensated by [M(1,10-phen){sub 2}] (M=Ni, Co) or [Ni(2,2'-bpy){sub 2}] subunits. The thermogravimetric analyses and magnetic properties of 1 and 2 were studied.
