摘要：

A new tetranuclear nickel compound, showing mu-CO3 bridges and butterfly topology has been synthesised and structurally characterised. The complex [Ni-4(mu-CO3)(2)(aetpy)(8)][ClO4](4), where aetpy corresponds to (2-aminoethyl)pyridine, crystallises in the tetragonal system, space group P4(2)2(1)2 (no. 94), a = 14.523(4), c = 16.566(5) Angstrom and Z = 8. Magnetic measurements show an overall antiferromagnetic behaviour with a quasi-degenerate set of spin levels S = 0, S = 1 and S = 2 as a ground state, which may be rationalised in terms of a spin frustration system.
