Synthesis and study of new clathrochelates with 1-phenyl-2-(1'-piperidinyl) ethanone oxime ligand

The synthesis and characterization of new complex compounds of [M(L-H)X-2], [ML(L-H)]X and [M(L-H)(2)] types (M= Co, Ni, Cu, X = Cl, CH3COO) and L=[-p henyl-2-(1'-piperidinyl) ethanone oxime is presented. In reactions of [ML(L -H)]X (M = Ni, Cu) with Lewis acids like TiCl4 and SnCl4 semiclathrochelate s of [M(L-H)(2)MCl2] type (M'=Ti, Sn) were obtained and characterized (elec tronic, FT-IR, RPE, NMR spectra, conductivity measurements, as well as TD-a nalysis). Such complexes should be potential oxygen molecular carriers.
