A novel yttrium (Ⅲ) coordination compound supported by plenary Dawson cluster, [Y(NMP)5(H2O)2] [Y(NMP)4(H2O)2(P2Mo18O62)]·NMP·5.5 H2O, (NMP = N- methyl-2-pyrrolidone) has been synthesized by reaction of α-H6P2Mo18O62·nH2O, Y2O3 and NMP in water. The results of the single crystal X-ray diffraction analyses show the title compound forms a neutral and discrete cluster through [P2Mo18O62]6- being coordinated to [Y(NMP)4(H2O)2]3+ through its terminal oxygen atom.
