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) A. 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) A.Dedicated to the memory of Dr Leigh C. Porter (1955–1999).
