A hydrogen atom at the center of an octahedral cage of cobalt atoms —that is a striking structural feature of the title compound which is the first of its kind to be accurately characterized by neutron diffraction in a single crystal. Only few examples of such “interstitial” hydride ligands are known for covalent complexes. The apparent radius of the H atom is 0.53Å; it can readily enter and leave its “metal cage”.
