The reaction of phenyl 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: C36 H30N8O11Cu3,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)(A)3,Z= 8,Dc = 1.566g/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 antisymmetric exchange.
