摘要：

Two new metal-organic polymers (MOPs): [Mn-2(Hoba)(4)4H(2)O](n) (1), [Mn-2(dpb)(2)(oba)(2)H2O](n) (2), (H(2)oba = 4,4 '-oxybis(benzoic acid), dpb = 1,4-bis(pyridin-3-ylmethoxy) benzene), have been synthesized under hydrothermal conditions and structurally characterized by single-crystal X-ray diffraction. Compound 1 exhibits a two-dimensional (2D) wave layer structure with 4(4)6(2) topology which containing a meso-helical chain. Compound 2 features a 1D bicyclo-chain with (4(3))(2)(4(6).6(5).8(3).10) topology built up from linear 3-connected oba(2) , 2-connected dpb and 6-connected secondary building units (SBUs) [Mn-2(COO)(4)H2O]. Their structures are further characterized by elemental analysis (EA), infrared spectrum (IR), powder X-ray diffraction (PXRD), and thermogravimetric analyses (TG), moreover, temperature- dependent magnetism susceptibility measurements show antiferromagnetic characters for compounds 1 and 2.
