Synthesis and crystal structure of two novel polymeric PbII compounds: [Pb(phen)(N3)2]n and [Pb(deta)(N3) · (N3)]n

Abstract Two novel 1D polymeric Pb(II) complex containing the Pb 2 -(μ-N 3 ) 2 units, [Pb(phen)(N 3 ) 2 ] n ( 1 ) and [Pb(deta)(N 3 ) · (N 3 )] n (2) (deta and phen are the abbreviations of diethylentriamine and 1,10-phenanthroline, respectively) have been synthesized and characterized by single-crystal X-ray diffraction. Compounds of ( 1 ) and ( 2 ) are six, PbN 6 , and five, PbN 5 , coordinated polymers, respectively. Both of them hold hemidirected coordination geometries. To the best of our knowledge, these 1D coordination polymers are the novel Pb 2 -(μ-N 3 ) 2 units of lead(II) compounds and interact with each other via π–π stacking and weak Pb⋯N interactions to create 3D and 2D frameworks.
