Diffusion of large amine ligands into layered α-Zr(HPO4)2·H2O. Access to a solid-state co-ordination chemistry
Abstract
2,2′-Bipyridyl and 1,10-phenanthroline can be diffused between the layers of pre-swelled α-Zr(HPO4)2·2H2O to give the materials α-Zr(HPO4)2[bipy]0.25·1.5H2O and α-Zr(HPO4)2[phen]0.5·2H2O; metal ions co-ordinate preferentially ot the stage I dispersed ligand with in situ formation of complex pillars.
