摘要	Thirteen novel 3d-4f heteronuclear coordination polymers based on the pyridine-2,6-dicarboxylic acid (H(2)pda) and imidazole ligands, HIm[(pda)(3)MLn(Im)(2)(H(2)O)(2)]center dot 3H(2)O (Im = imidazole; M = Co, Ln = Pr (1), Gd (2), Dy (3), Er (4); M = Mn, Ln = Pr (5), Sm (6), Gd (7), Dy (8), Er (8)), HIm[(pda)(3)CoSm(Im)(2) (H(2)O)(2)]center dot 2H(2)O (10), [(Im)(4)M(H(2)O)(2)][(Pda)(4)La(2)(H(2)O)(2)]center dot 2H(2)O (M = Co (11), Mn (12)), and [(Pda)(6)CO(3)Pr(2) (H(2)O)(6)]center dot 6H(2)O (13), have been prepared and structurally characterized. X-ray crystallographic analyses revealed that these complexes display four different types of structures. Complexes 1-9 are isostructural, and possess 1-D chain structures constructed by alternately arrayed nine-coordinated Ln(III)(Ln = Pr, Sm, Gd, Dy, Er) and six-coordinated M(II) (M = Mn, Co) ions. Complex 10 exhibits a unique one-dimensional structure, in which two independent chains are parallel viewed down the a-axis and anti-parallel viewed down the c-axis. Complexes 11 and 12 are isostructural and display 1-D homometallic chain structures. Complex 13 is a 3D framework fabricated through PrN(3)O(6) and CoO(6) polyhedrons as building blocks. The variable-temperature solid-state dc magnetic susceptibilities of complexes 2, 3, 4, 9 and 13 have been investigated. Antiferromagnetic exchange interactions were determined for these five complexes. (C) 2011 Elsevier Ltd. All rights reserved.
