摘要
A novel manganese 5-carboxyl-1-carboxymethyl-3-oxidopyridinium (H(2)L) metal-organic framework has been synthesized and characterized using single-crystal X-ray diffraction analysis. The structure can be considered as constructed of 2D layers consisting in left-and right-handed helical chains and further linked by L(2-) ligands into a 3D (4,8)-connected fluorite network with a Schlafli symbol of (4(6))(2)(4(12).6(12).8(4)). The magnetic susceptibility data are interpreted with the dimer law, yielding J and g values of 0.94(2) cm(-1) and 1.97(2). The exchange integral (J) indicates that there is a weak ferromagnetic interaction between two Mn(2+) ions.
