In the title Pb(II) complex, Pb(2)(C(2)Cl(3)O(2))(2)(NO(3))(2)(C(12)H(8)N(2))(2), the 1,10-phenanthroline ligand is chelating, the nitrate anion chelates one Pb(II) ion and simultaneously bridges a neighbouring Pb(II) ion via the third O atom, and the trichloro-acetate anion is bidentate, bridging two Pb(II) ions. The coordination geometry is based on a penta-gonal-bipramidal geometry defined by an N(2)O(5) donor set with no obvious stereochemical role for the lead-bound lone pair of electrons. The coordination polymer has a zigzag topology along [010] and comprises alternating eight-membered {PbONO}(2) and {PbOCO}(2) rings.
在标题为Pb(2)(C(2)Cl(3)O(2))(2)(NO(3))(2)(C(12)H(8)N(2))(2)的Pb(II)配合物中,1,10 - 菲咯啉配体为螯合配体,硝酸根阴离子螯合一个Pb(II)离子,同时通过第三个O原子桥连相邻的Pb(II)离子,三氯乙酸根阴离子为双齿配体,桥连两个Pb(II)离子。配位几何构型基于由N(2)O(5)供体集定义的五角双锥几何构型,铅结合的孤对电子没有明显的立体化学作用。该配位聚合物沿[010]具有锯齿状拓扑结构,由交替的八元{PbONO}(2)和{PbOCO}(2)环组成。
