title: An azido-bridged disc-like heptanuclear cobalt(II) cluster: towards a single-molecule magnet.
abstract: A disc-like heptanuclear Co(II)-cluster, [Co7(bzp)6(N3)9(CH3O)3].2ClO4.2H2O (1) (bzp = 2-benzoyl pyridine), mixed-bridged by 3/4 azides (mu1,1 and mu1,1,1) and 1/4 mu1,1,1-methanol, shows slow relaxation at static zero and non-zero fields below 6 K, towards single molecule magnet behavior.
