Solid-State Syntheses of Coordination Polymers by Thermal Conversion of Molecular Building Blocks and Polymeric Precursors
The syntheses and crystal structures of a mononuclear
cadmium complex
and five novel coordination polymers based on 1,2,4-triazolyl benzoates
are presented. The compounds <sub>∞</sub><sup>3</sup>[CdÂ(H-Me-trz-<i>p</i>ba)<sub>2</sub>] (<b>2</b>), <sub>∞</sub><sup>3</sup>[CdÂ(Me-3py-trz-<i>p</i>ba)<sub>2</sub>] (<b>4</b>), and <sub>∞</sub><sup>3</sup>[ZnÂ(H-Me-trz-<i>p</i>ba)<sub>2</sub>] (<b>6</b>) can be obtained by solvothermal synthesis or simple
heating of the starting materials in appropriate solvents, and are
also accessible by thermal conversion of the complex [CdÂ(H-Me-trz-<i>p</i>ba)<sub>2</sub>(H<sub>2</sub>O)<sub>4</sub>] (<b>1</b>), the one-dimensional (1D) coordination polymer <sub>∞</sub><sup>1</sup>[CdÂ(Me-3py-trz-<i>p</i>ba)<sub>2</sub>(H<sub>2</sub>O)<sub>2</sub>]·H<sub>2</sub>O (<b>3</b>), and the porous three-dimensional (3D)
framework <sub>∞</sub><sup>3</sup>[ZnÂ(H-Me-trz-<i>p</i>ba)<sub>2</sub>]·4H<sub>2</sub>O (<b>5</b>), respectively. The driving force for these
conversions is the formation of thermally stable, nonporous, crystalline
3D coordination polymers. The structural transformations are accompanied
by the loss of water and reveal significant changes of the coordination
spheres of the metal ions caused by a rearrangement of the triazolyl
benzoate ligands. Compounds <b>2</b>, <b>4</b>, <b>5</b>, and <b>6</b> exhibit 4- and 5-fold interpenetration
of diamondoid networks (<b>dia</b>) and are thermally stable
up to 380 °C
