Co3H is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a distorted body-centered cubic geometry to four equivalent Co(2) and four equivalent H(1) atoms. In the second Co site, Co(2) is bonded in a body-centered cubic geometry to eight equivalent Co(1) atoms. H(1) is bonded in a body-centered cubic geometry to eight equivalent Co(1) atoms.
