An unusual case of symmetry-preserving isomerism.
Two isomeric phases of the NbO-type structure have been discovered: PCN-16 (alpha phase) and PCN-16' (beta phase), and gas sorption studies revealed that the alpha phase possesses a larger surface area, leading to higher hydrogen and methane storage capacity as compared with the beta phase.
