| 摘 要： | Hydrothermal reactions of 5-(pyridin-2-yl-methyl)aminoisophthalic acid(H2paip) with Mn(OAc)2·4H2O and Cu(NO3)2·3H2O produced two 2D complexes, Mn(paip)]n·nH2O(1) and Cu(paip)(H2O)]n(2). In complex 1, paip serves as a μ4-bridge, and its two carboxylate groups in μ2,η2-bridging and chelating modes connect Mn(Ⅱ) into 1D chains, which are further extended into a 2D layer through coordination of two chelating nitrogen atoms. However, paip in complex 2 acts as a μ3-bridge to link Cu(Ⅱ) into a 2D layer, in which two carboxylate groups function in a monodentate mode, and hydrogen bonds between the coordinated water and carboxylate oxygen atoms further extend the 2D layers into a 3D supramolecular network. The frameworks of complexes 1 and 2 are stable up to 470 and 250 ℃, respectively. Magnetic measurement shows that complex 2 possesses a weak antiferromagnetic interaction.
