Y. Gok et al., AXIAL-LIGATION AND MACROCYCLIZATION OF NOVEL (E,E)-DIOXIMES OF NICKEL(II), PALLADIUM(II), PLATINUM(II) AND COBALT(III), Transition metal chemistry, 20(3), 1995, pp. 234-238
The synthesis and characterization of new Ni-II, Pd-II, Pt-II and Co-I
II complexes, with the BF2+-bridged, bis(alpha-dioximato) ligands are
described. The initially formed six-coordinate hydrogen-bonded macrocy
cles, were used as metal templates to prepare the corresponding BF2+-c
apped macrocycles. The complexes were characterized by H-1-n.m.r. and
i.r, spectroscopy, and by elemental analysis.
