Abstract
One complex with a zwitterionic dicarboxylate ligand, [Mn(L)(N 3)]n 1 (L = 1-carboxymethylpyridinium-3-carboxylate), was synthesized and structurally characterized. Complex 1 crystallizes in triclinic, space group P-1 with a = 7.570(2), b = 7.808(2), c = 9.232(3) Å, β = 94.450(19)°, V = 489.0(3) Å3, Z = 2, Mr = 277.11, Dc = 1.882 g/cm3, F(000) = 278, μ = 1.359 mm-1, S = 1.021, the final R = 0.0509 and wR = 0.1149 for 2236 observed reflections with I > 2σ(I). Complex 1 consists of two-dimensional coordination layers in which the anionic uniform chains with mixed triple bridges (one end-on (EO) azide and two syn-syn carboxylates) are cross-linked by the flexible cationic N-methylpyridinium spacers. Magnetic studies demonstrated that the triple bridge in 1 transmits antiferromagnetic coupling between the Mn(II) ions.
