摘要
The reaction of phenyl 2-pyridyl ketoxime (PhPyCNOH) with Cu(NO3)(2)center dot 3H(2)O has led to a triangular complex Cu-3(OH)(PhPyCNO)(3)(NO3)center dot NO3 center dot H2O 1 containing the [Cu-3(mu(2)-OH)](5+) core and possessing the very rare inverse 9-metallacrown-3 motif created by the bridging oximate groups. Crystallographic data for 1: C36H30N8O11Cu3, M-r = 941.30, monoclinic, space group C2/c, a = 18.815(9), b = 33.888(15), c = 14.307(7) angstrom, beta = 118.945(6)degrees, V = 7983(6) angstrom(3), Z= 8, D-c = 1.566 g/cm(3), mu = 1.652 mm(-1), F(000) = 3816, R = 0.0644 and wR = 0.1393 for 3468 observed reflections (I > 2 sigma(I)). Preliminary variable-temperature magnetic susceptibility studies reveal an antiferromagnetically-coupled system showing antisymmetric exchange.
