合成了混合价钨钼混配杂多化合物[C10H10N]4PMo9W3O40·2DMF,晶体属单斜晶系,空间群P21/n,a=1.490 6(4) nm,b=1.249 6(1) nm,c=1.765 2(5) nm,β=98.16(1)°,V=3.254 7(13) nm3,Z=2,Dc=2.791 Mg/m3,Mr=2 735.84,最终偏离因子R=0.053 1,Rw=0.136 2.晶体结构研究表明,钨原子取代钼以后阴离子中所有键长均有不同程度的改变,PO4四面体畸变增大.ESR研究表明,还原电子在钼原子间离域且其离域程度随温度降低而减弱;非线性光学性质测定显示化合物具有三阶非线性光学性质,χ(3)=1.48×10-13 esu.
