Cyclopentadienyl chromium hydrazide gels were synthesized from the protonolysis reaction between bis(cyclopentadienyl) chromium and hydrazine. The amorphous products containing low valent chromium species are exploited as substrates for Kubas-type hydrogenstorage. These materials demonstrate enthalpies that rise from 10 to 45 kJ mol-1 and show a retention of 49% of the adsorption capacity at 298 K relative to 77 K, compared to values of 10–15% for most MOFs and amorphous carbons.
