%X A series of novel double helicates, {AMo2ⅥO4LnⅢ (H2O)6(C4H2O6)2]·4H2O}n(Ln =Sm, Eu, Gd, Ho, Yb, Y; C4H2O6 = L-tartaric acid; A = NH4 or H3O), have been synthesized from the reactions of chiral ligands L-tartaric acid with molybdates as well as lanthanide cations. The architectures of these compounds are one dimensional enantiopure novel right- or left-handed double helical one-dimensional chains, which are somehow like DNA in general configurations. By the hydrothermal reaction method, some molybdenum oxide units such as { MoO4 }, { Mo2 O7 } , { Mo8 O26 } are linked up by transition metal/organic ligand fragments to novel zero-, one-, two- or three-dimensional structures. Most of these compounds have voids, which are occupied by some suitable crystallization herterometallate chemistry containing lanthanide cations that is synthesized by the hydrothermal reaction.The compound is built up by Silverton-type GdMo12O42 ]9- anions linking up nine coordinated Gd3+cations. It is the first example for introducing a paramagnetic lanthanide cation into the Silverton-type anionic center, which provides a very interesting example for the further synthesis of such a kind of compound/polymer. One-dimensional polymer, Cu2 ( C8 H6 N2 )2 ( C7 H6 N2 ) ] 2 Mo8 O26 ], which consists of β- Mo8 O26 ]4- anions linked by quinoxaline and its oxidized product benzimidazole ligands coordinating binuclear copper(Ⅰ) fragments, provides the first example that the isolated copper(Ⅰ) complex under hydrothermal conditions "captures" the reduction product of original starting organonitrogen ligand to form a copper( Ⅰ )-β-octamolybdate complex.
