Amorphous Infinite Coordination Polymer Microparticles: A New Class of Selective Hydrogen Storage Materials

A new class of micrometer-sized amorphous infinite coordination particles is selectively prepared from the coordination chemistry of a metallo-salen building block and Zn2+ ions. The particles show moderately high H2 uptake and almost no N2 adsorption, even though they are amorphous and do not have the well-defined channels typically used to explain such selectivity in metal–organic framework systems.
