Synthesis,Characterization, and Crystal Structure of a New Coordination Polymer of Lead(II) Containing 2,6‐Pyridinedicarboxylic Acid

The reaction of solution 2,6‐pyridinedicarboxylic acid ( 1 ) and 2,2′‐Bipyridine with Pb(NO₃)₂ led to the coordination polymer [Pb(pydc)]_n ( 2 ) (pydcH₂ is 2,6‐pyridinedicarboxylic acid). This complex was characterized by elemental analysis, IR spectroscopy and single‐crystal structure of 2 . Crystal data for 2 at ?80 °C: monoclinic, space group P2₁/n, a = 977.2(1), b = 554.0(1), c = 1425.3(2) pm, β = 104.75(1)°, Z = 4, R₁= 0.0261. The units [Pb(pydc)] form infinite chains along [010].
