A Novel Periodic Entanglement Lead(II) Coordination Polymer Nets

The synthesis and characterization of infinite two- and three-dimensional networks has been an area of rapid growth in recent years [1]. The motivation behind much of this activity has been provided by the prospect of generating, by deliberate design, a wide range of purpose-built materials with predetermined structures and useful properties, for example electronic, magnetic, optical, and catalytic. Implicit or explicit in much of this work has been the idea of self-assembly of specifically designed building blocks. There is still a long way to go in the development of this field before it will be possible to say that these ambitious objectives have been fully realized. Nevertheless, great opportunities for exciting advances are provided by the enormous sweep of chemistry embracing coordination, organic, and main group chemistry, which is at our disposal for creative use in the planned construction of frameworks [2,3]. Herein, we report a novel leadII coordination polymer nets, ordered by periodic entanglement of polydentate aromatic amine and useful counter ions in a shape step-like nets.
