The title coordination polymer, Pb(2)(N(3))(3)(NO(2))(C(12)H(8)N(2))(2), has as the repeat unit a centrosymmetric dinuclear mol-ecule having azide and nitrite groups that bridge adjacent heterocycle-coordinated metal centers. One of the azide group uses its terminal ends to bridge whereas the nitrite group chelates to one metal atom and uses one of its O atoms to bridge. The azide and nitrite groups are disordered with respect to each other in a 1:1 ratio. Adjacent dinuclear mol-ecules are further bridged by the other two azide groups, generating a linear chain motif parallel to [010]. Half of the Pb atoms show a Ψ-dodeca-hedral coordination and the other half show a Ψ-penta-gonal-bipyramidal coordination.
标题配位聚合物[Pb₂(N₃)₃(NO₂)(C₁₂H₈N₂)₂]ₙ的重复单元是一个中心对称的双核分子，其中叠氮基和亚硝酸根基团桥连相邻的杂环配位金属中心。一个叠氮基用其末端进行桥连，而亚硝酸根基团螯合一个金属原子并利用其一个O原子进行桥连。叠氮基和亚硝酸根基团以1:1的比例相互无序排列。相邻的双核分子通过另外两个叠氮基进一步桥连，形成平行于[010]的线性链状结构。一半的Pb原子呈现Ψ-十二面体配位，另一半呈现Ψ-五角双锥配位。
