摘要
Addition of 1,2-phenylenediamine to solutions of bis(1,1,1,5,5,5-hexafluoropentane-2,4-dionato-O,O')coblat(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) Angstrom. 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) Angstrom.
