摘要：

Metal complexes of the type ML2 [M = Co(II), Ni(II), Cu(II); L 1-hydroxy-2-naphthyl(4-X-styryl)ketoneoximes (HNXSKOx), (X = H, Me, MeO)] have been synthesized. All the chelates are anhydrous. The copper complexes possess trans-square-planar geometry and the nickel and cobalt complexes have low-spin trans-square-planar configuration. As the conjugation of C=N with Ph-C=C is inhibited, the basic nature of oximino nitrogen is not affected. The strong M-N sigma-bond leads to enhanced ligand field strength and spin-pairing.
