J. Ribas et al., VERSATILITY OF THE AZIDO BRIDGING LIGAND IN THE FIRST 2 EXAMPLES OF FERRO-ANTIFERROMAGNETIC ALTERNATING NICKEL(II) CHAINS, Journal of the Chemical Society, Chemical Communications, (23), 1995, pp. 2375-2376
A one-pot reaction of Ni(ClO4)(2) . 6H(2)O, N,N-dimethylethylenediamin
e (dmen) or 2-aminoethylpyridine (aep) and NaN3 affords the two [Ni(dm
en)(mu-N-3)(2)](n) 1 and [Ni(aep)(mu-N-3)(2)](n) 2 chains with unprece
dented alternating end-on and end-to-end bridging loops perpendicular
to one another; magnetic susceptibility measurements indicate that the
y are the first two ferro-antiferromagnetic alternating chains of Ni-I
I.
