Abstract: | Addition of 1,2‐phenylenediamine to solutions ofbis(1,1,1,5,5,5‐hexafluoropentane‐2,4‐dionato‐O,O′)cobalt(II),‐iron(II) and ‐nickel(II) resulted in crystals containing centrosymmetric octahedral complexes with two amines per metal atom. In all three isostructural complexes, i.e. M(C5HF6O2)2(C6H8N2)2] where M = Fe, Cu and Ni, the two C—N bonds differ significantly in length by an average of 0.031 (3) Å. The phenyl C—C bonds display a pattern of small differences, the C—C bond between the amines being longer than the shortest phenyl C—C bonds by an average of 0.022 (4) Å. |
