Abstract

A new heptanuclear compound [{Co(TPA)CN}₆Fe][PF ₆]₈ (1) (TPA = tris(2-pyridylmethyl)amine) was constructed by the reaction of [Co(TPA)]^{2 +} cations and K₃Fe(CN) ₆. The cyanometalate core is capped by six mono-nuclear cobalt units via the cyanides. 1 crystallizes in triclinic space group C2 with a = 19.5720 Å, b = 26.2450 Å, c = 16.3820 Å, β = 118.500° and Z = 2. Variable temperature magnetic measurements have demonstrated that very weak antiferromagnetic interaction between the nearest paramagnetic Co^II centers is exhibited. Thus weak antiferromagnetic coupling might be transferred by NCFeCN bridging units.
