Abstract

The reaction of phenyl 2-pyridyl ketoxime (PhPyCNOH) with Cu(NO ₃)₂·3H₂O has led to a triangular complex Cu₃(OH)(PhPyCNO)₃(NO₃)·NO ₃·H₂O 1 containing the [Cu₃(μ ₂-OH)]⁵⁺ core and possessing the very rare inverse 9-metallacrown-3 motif created by the bridging oximate groups. Crystallographic data for 1: C₃₆H₃₀N₈O₁₁Cu ₃, M_r = 941.30, monoclinic, space group C2/c, a = 18.815(9), b = 33.888(15), c = 14.307(7) Å, β = 118.945(6)°, V = 7983(6) Å³, Z = 8, D_c = 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 antiferroma-gnetically-coupled system showing antisymmetric exchange.
