title: catena-Poly[[(1,10-phenanthroline-κN,N')lead(II)]-μ-azido-κN:N-μ-nitrito-κO,O':O'-[(1,10-phenanthroline-κN,N')lead(II)]-di-μ-azido-κN:N].
abstract: The title coordination polymer, [Pb(2)(N(3))(3)(NO(2))(C(12)H(8)N(2))(2)](n), 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.
