SYNTHESIS AND REACTIVITY IN INORGANIC AND METAL-ORGANIC CHEMISTRY
Two cationic mixed-ligand complexes. [Co(L)cyc]NO3. C2H5OH (A) and [Co-2(L)
tpmc](ClO4)(2) CH3CN (B), were prepared. where cyc = 1,4,8,11-tetraaza-cycl
otetradecane, tpmc = N,N',N",N"'-tetrakis(2-pyridylmethyl)-1,4,8,11-tetraaz
a cyclotetradecane and L = bicyclo[2.2.1]-hept-5-en-endo-2,3-cis-dicarboxyl
ate dianion. The complexes were characterized by elemental analyses, ion-ex
change chromatography, magnetic moments, conductance measurements, IR, C-13
NMR and UV/VIS spectroscopy and cyclic voltammetry. It is suggested that t
he complexes A and B have octahedral structures with endobidentate or exo-(
bis)-bidentate coordination of L.
