由一维混合价态铁和钼磷酸盐与金属络合物组成的两种复合固体，[（C10H8N2）3FeII] 3FeII2FeIII2MoV24（H2PO4）8（HPO4）4（PO4）4O48（OH）12（H2O）4·12H2O（1）和[（C10H8N2）3FeII] 2FeIIFeIIIMoV12（H2PO4）2（H2 − xPO4）（H1 + xPO 4）（HPO 4）2（PO 4）2 O24（OH）6（H2O）2·9 H2O（x = 0 - 1）（2），其中一维无机阴离子由交替的[FeII（P8 Mo12）]单元和FeIII离子构成，通过MoO3、H3 PO 4、Fe2（C2 O4）3·5 H2O、2、2 ′-联吡啶、H2C2O4·2H2O和H2O，并通过元素分析和单晶X射线衍射进行了表征。虽然在阴离子链中Mo、Fe、P、O之间的非氢原子比相同，但PO4基团的质子化在1和2中不同，结果是阴离子链携带不同的电荷，并且随后产生每{FeIII2 [FeII2（P16MoV24）]}单元不同数量的FeII（2，2 ′-联吡啶）3。
Two composite solids consisting of one-dimensional mixed-valence iron and molybdenum phosphates with metal complexes, [(C10H8N2)3FeII]3FeII2FeIII2MoV24(H2PO4)8(HPO4)4(PO4)4O48(OH)12(H2O)4·12H2O (1) and [(C10H8N2)3FeII]2FeIIFeIIIMoV12(H2PO4)2(H2 − xPO4)(H1 + xPO4)(HPO4)2(PO4)2O24(OH)6(H2O)2 ·9H2O (x = 0–1) (2), in which the one-dimensional inorganic anions are constructed of alternating [FeII(P8Mo12)] units and FeIII ions, were synthesized by hydrothermal reaction of MoO3, H3PO4, Fe2(C2O4)3·5H2O, 2,2′-bipyridine, H2C2O4 ·2H2O and H2O, and characterized by elemental analysis and single-crystal X-ray diffraction. Though the non-hydrogen atomic ratios among Mo, Fe, P, O in the anionic chains are the same, the protonation of the PO4 groups is different in 1 and 2, with the result that the anionic chains carry different charges and subsequently give rise to different numbers of FeII(2,2′-bipyridine)3 per {FeIII2[FeII2(P16MoV24)]} unit.
