| Abstract: | A three-dimensional coordination polymer Mn2((1,3-N3)4(μ-PP)2]n (PP = 3-(pyra- zin-2-yloxy)-pyridine) has been synthesized with 3-(pyrazin-2-yloxy)-pyridine and azide anion as mixed bridge ligand, and its crystal structure was determined by X-ray crystallography. The crystal data: triclinic system, space group P, with a = 6.794(4), b = 9.885(6), c = 9.947(6)A, α = 64.170(6),β = 84.190(8),γ = 85.319(8)°, V = 597.7(6)(A)3, Z = 1, C18H14Mn2N18O2, Mr = 624.35, Dc = 1.735 g/cm3, F(000) = 314 andμ= 1.117 mm-1. In the crystal, the azide anion acts as a bridge ligand and makes adjacent Mn(Ⅱ) ions connect into a two-dimensional sheet on the ab plane, then 3-(pyrazin-2-yloxy)-pyridine serves as a bidentate bridge ligand to connect neighboring sheets along the c axis, and finally a three-dimensional structure is formed. |
