The crystal structures of Fe(NCNH) 2 and Co(NCNH) 2 , isotypical with Ni(NCNH) 2 , have been refined by means of combined X‐ray and neutron powder diffraction data (SPODI, FRM II). The lattice parameters are a = 6.6655(7), b = 8.7923(8), c = 3.3304(3) Å for Fe(NCNH) 2 and a = 6.5696(2), b = 8.8058(2), c = 3.2622(1) Å for Co(NCNH) 2 in the orthorhombic system Pnmm (no. 58). The positions of the hydrogen atoms have been clearly resolved.
