[CoII(phen)3]2[{(ZnW12O40)CoII(phen)2(H2O)}2CoII(trien)2(NaH2O)2]·3H2O was synthesized via hydrothermal technique and characterized with elemental analyses, IR spectroscopy, TGA-DTA, and variable temperature magnetic susceptibility. The compound crystallized in the monoclinic system with the space group P21/n, a=1.8210 nm, b=2.3592 nm, c=2.2932 nm, β=110.31o, V=9.239 nm3, Z=2, R1=0.0827. The compound consists of two coordination cations, three lattice water molecules, and a macroanion [{(ZnW12O40)Co(phen)2(H2O)}2Co(C6H18N4)2· (NaH2O)2]4- in which each supported Keggin anion [(ZnW12O40CoII(phen)2(H2O)]4- acts as a ligand to coordinate to central bridging Co2+ ion via a terminal oxygen atom. Hydrogen bonds are responsible for the construction of 3D architecture of the compound. The compound is paramagnetic with a weak antiferromagnetic interaction(θ=-46.796 K).
