摘      要：The reaction ofphenyl 2-pyridyl ketoxime （PhPyCNOH） with Cu（NO3）2·3H2O has led to a triangular complex Cu3（OH）（PhPyCNO）3（NO3）·NO3·H2O 1 containing the [Cu3（μ2-OH）]5＋ core and possessing the very rare inverse 9-metallacrown-3 motif created by the bridging oximate groups. Crystallographic data for 1： C36H30N8O11CU3, Mr = 941.30, monoclinic, space group C2/c, a = 18.815（9）, b = 33.888（15）, c = 14.307（7） A, β = 118.945（6）°, V= 7983（6） A3, Z = 8, Dc = 1.566 g/cm3, μ = 1.652 mm^-1, F（000） = 3816, R= 0.0644 and wR= 0.1393 for 3468 observed reflections （I〉 2σ（I））. Preliminary variable-temperature magnetic susceptibility studies reveal an antiferromagnetically-coupled system showing antisymmetrie exchange.
