| Popis: | Changes in the synthetic procedures for making metal phosphonate materials can lead to whole new structure types. Using a eutectic mixture of urea and choline chloride as the reaction medium for a reaction between zinc acetate and diethylphosphonacetic acid gives rise to Zn(O 3 PCH 2 CO 2 H) · H 2 O, which has a new porous structure. Replacing divalent transition metal cations with Pb 2+ in the synthesis of a vinylphosphonate, Pb(O 3 PCH CH 2 ), gives rise to a new porous structure that has not previously been observed for vinylphosphonates. In this case it is the ability of the Pb 2+ ions to adopt co-ordination environments other than octahederal or tetrahedral that allows the structure to form. |
