A new 3-D La(lll)-Cu(ll) Containing Coordination Polymer with High Potential Porosity.
Résumé
A new 3-D coordination polymer containing both 3d and 4f ions has been designed. Its chemical formula is La2[Cu(pba)]3(H2O)8•8H2O. It crystallizes in the quadratic system, space group I41/a with a = 42.4947(9) Å, c = 16.3378(3) Å, and Z = 16. Its crystal structure can be described as a 3-D molecular framework exhibiting a complex network of interconnected zigzaglike channels. Once crystallization water molecules are removed, this compound presents a high potential porosity and a low density. The porosity has been evaluated using Connolly's algorithm.
