Abstract
We report the synthesis of hydrogen-bonded frameworks prepared from guanidinium, bis-amidinium, or tetra-amidinium cations and diphosphonate or tetraphosphonate anions. The frameworks are assembled by both charge-assisted amidinium···phosphonate and antielectrostatic phosphonate···phosphonate hydrogen bonds, of which the phosphonate···phosphonate interactions are notably shorter. Frameworks prepared from the tetrahedral tetraphosphonate building block contain relatively large water-filled channels but lose crystallinity upon drying. The crystal structure of a guanidinium···diphosphonate salt has an unusual structure related to classic Ward guanidinium···sulfonate frameworks but with an additional cation/solvent layer. This material includes toluene guests, which are held strongly within the crystal lattice.
期刊介绍:
The aim of Crystal Growth & Design is to stimulate crossfertilization of knowledge among scientists and engineers working in the fields of crystal growth, crystal engineering, and the industrial application of crystalline materials.
Crystal Growth & Design publishes theoretical and experimental studies of the physical, chemical, and biological phenomena and processes related to the design, growth, and application of crystalline materials. Synergistic approaches originating from different disciplines and technologies and integrating the fields of crystal growth, crystal engineering, intermolecular interactions, and industrial application are encouraged.
