A new metal-organic complex, {[Co (C 12 H 10 N 4) 2 (H 2 O) 4] 獉 2C 4 H 3 O 4} n (C 12 H 10 N 4 = 4-bpdb = (1,4-bis (4-pyridyl) -2,3-diaza-1,3-butadiene, C_4H_3O_4 = fumaric acid) The structure of this compound was determined by X-ray single crystal diffraction The results show that the compound belongs to the triclinic and P-1 space group with unit cell parameters of a = 0.628 95 (3) nm, b = 0.701 07 (3) nm and c = 2.088 38 , β = 92.502 (2) °, Z = 1, V = 844.038 (7) nm ~ 3, Dc = 1.537 mg / m ~ 3, Mr = 781.60, Z = 1 and μ = 0.586 mm ~ F (000) = 405, R_1 = 0.029 9, wR_2 = 0.091 6. The central ion Co (Ⅱ) coordinates with the N atoms in the two 4-bpdb organic ligands and the O atoms in the four water molecules by means of The interaction between the coordination water molecules and the uncoordinated fumaric acid molecules and the π ... π stacking effect between the aromatic rings of the organic ligands finally form a two-dimensional supramolecular network The results of magnetic properties show that the complex has a weak antiferromagnetic property, T_θ = -2.99 K.
