摘要：

The reaction of di-2-pyridyl ketone, (2-py)(2)CO, with Ni(O2CMe)(2). 4H(2)O yields the cage [Ni-9(OH)(2)(O2CMe)(8){(2-py) 2CO2}(4)], which reacts further with N-3(-) ions to give the structurally similar cluster [Ni-9(N-3)(2)(O2CMe)(8){(2-py) 2CO2}(4)] containing extremely rare eta (1),mu (4)-N-3(-) groups; magnetic studies reveal that the spin ground state of the latter is nine times the ground state of the former.
