Abstract

Selective recovery of the guest-framework interactions for H(2) adsorbed in a nanoporous Prussian Blue analogue, through differential X-ray and neutron pair distribution function analysis at ca. 77 K, suggests that the H(2) molecule is disordered about a single position at the centre of the pore, ((1/4),(1/4),(1/4)), without binding at accessible Mn(II) sites.
