  摘要：

  The title compound, (2,6-diacetylpyridine bis{[2-(hydroxyimino) propanoyl] hydrazone}(2-)) nickel(II) dimethyl sulfoxide solvate monohydrate, [Ni(C15H17N7O4)]center dot C2H6OS center dot H2O, represents the first example of square-planar N-4 coordination via N atoms with four different functions, namely amide, azomethine, hydroxyimino and pyridine. The coordination polyhedron of the central Ni atom has a slightly distorted square-planar geometry. The 2,6-diacetylpyridine bis{[ 2-(hydroxyimino) propanoyl] hydrazone} ligand forms one six- and two five-membered chelate rings, and a pseudo-chelate ring through an intramolecular hydrogen bond with an amide group as donor and a deprotonated hydroxyimino group as acceptor, resulting in a pseudomacrocyclic arrangement.
