A three-dimensional coordination polymer [Mn2(μ1,3-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) ,α = 64.170(6),β = 84.190(8),γ = 85.319(8)°,V = 597.7(6) 3,Z = 1,C18H14Mn2N18O2,Mr = 624.35,Dc = 1.735 g/cm3,F(000) = 314 and μ = 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.

《孟子》中有这样一段话:“当尧之时,天下犹未平,洪水横流,泛滥于天下。草木畅茂,禽兽繁殖,五谷不登,禽兽逼人。兽蹄鸟迹之道,交于中国。”这是对远古时期先人生存环境的描述。当时,天下一片洪荒,野草丛生,乱木成林,鸟兽大量繁殖,对人类形成了严重的威胁,即使在中原地区,也都布满了鸟兽行走的印迹。这些印迹对人类的生存具有极其重要的意义,人们正是根据这些印迹来判断鸟兽的类别,如果是凶猛的鸟兽,则提高警惕,或
