Mixed Valence Complex

A new tetranuclear mixed-valence cobalt complex, namely di-μ2-azido-diazidodiethanolbis{μ2-2-[(hydroxyimino)methyl]-6-methoxyphenolato}bis{μ3-6-methoxy-2-[(oxidoimino)methyl]phenolato}dicobalt(II)dicobalt(III) ethanol disolvate, [CoII2CoIII2(C8H7NO3)2(C8H8NO3)2(N3)4(C2H5OH)2]·2C2H5OH, has been synthesized by the reaction of Co(OAc)2·4H2O (OAc is acetate) with 3-methoxysalicylaldoxime (H2mosao) in an ethanol solution. In the complex, the four Co cations all display distorted octahedral coordination environments and they are bridged by two κ2,κ1,κ1;μ3-mosao2−ligands, two κ2,κ2;μ2-Hmosao−ligands and two μ2-N3−anions to form a tetranuclear [Co4N4O4] cluster. Adjacent clusters are connected through weak C—H...N and C—H...O interactions, resulting in a two-dimensional supramolecular network parallel to theacplane. The magnetic properties of the complex have also been studied.

Successful Observation

Recent advances in solid state n.m.r. spectroscopy permit obervation of high-resolution dipolar spectra, and thus renewed consideration can be given to solid state n.m.r. as a tool for determining molecular structure. This is illustrated with 13 C and 14 N single-crystal spectra obtained with both one- and two-dimensional n.m.r. techniques. The successful observation of these spectra is due to the fact that many dipolar interactions are inhomogeneous, and for this reason it is also possible to obtain high-resolution dipolar spectra from powder samples. Methods that accomplish this goal are described and illustrated with 13 C - 1 H dipolar spectra.
