Crystal structure studies of the compounds reported to be chlorobis(dimethylglyoximato)(ligand)cobalt(llI), where the ligand is sulfanilamide or 4-chloroaniline, have been completed. An unusual ligand-induced proton shift (LIPS) has occurred so that the complexes are best formulated as chloro(dimethylglyoximato)(dimethylglyoxime)(ligand)cobalt- (111), where both neutral and dianionic dimethylglyoxime groups are found in one complex. The crystals of 1, Co-C14H24CIN6O7S where the ligand is sulfanilamide, are orthorhombic, space group P2i2i2i, with unit cell dimensions of a = 10.591 (1), b = 13.970 (2), and c = 14.270 (3) Á. The complex II, C0C14H24CI2N5O6 where the ligand is 4-chloroaniline, is triclinic, space group , with cell dimensions of a = 7.494 (3), b = 11.838 (4), and c = 13.758 (6) Á, and a = 106.31 (3), ß = 91.25 (3), and y = 112.79 (3)°. Both structures were determined using the heavy-atom method and refined by leastsquares methods to an R of 0.056 for the 1696 reflections used in the analysis of I and R of 0.047 for the 2000 reflections used in the case of II. The hydrogen atoms were located in both structures and were refined in the case of II. The most unusual feature in the two structures is the orientation of the benzene ring of both the sulfanilamide and 4-chloroaniline groups over the dianionic ligand. The various distances, orientation, etc., suggest a -type interaction between the ligand and dmg rings. The coordination of the weakly basic ligands has apparently induced a shift of a proton from one Hdmg group to the other, thereby enhancing the stability of the complex. The concept of LIPS should have important implications in biological systems.

All anions used in this study are able to form hydrogen bonds because of the high electronegativity of atoms, which they contain.…”

“…Aniline molecules do not contain functional groups which could cause a different orientation of these ligands through the formation of hydrogen bonds (NH 2 group of the aniline molecule is coordinated to the central atom and does not infl uence in any case the steric factor of the benzene ring, and for this reason it was excluded from the study). However, besides π-π interactions which are formed between the benzene ring and the metallocycle of the equatorial plane, in some cases week hydrogen bonds such as C-H···F or C-H···O were observed [44]. it was observed that anions and water molecules form their own supramolecular system under a complicated system of hydrogen bonds (Fig.…”

Abstract.A comparative study of the orientation of the axial ligands relative to the equatorial plane in Co(III) α-dioximates was performed. Co(III) α-dioximates obtained by us and those founded in Cambridge data base have been selected for this study. As a result of this study it was observed that anions from the external sphere and the solvent molecules contribute to the orientation of the axial ligands, such as thiocarbamide and selenourea. For the ligands such as aniline and sulfanilamide it is more advantageous the almost parallel orientation, when π-π interactions between the aromatic rings of the ligand and metallocycle of the equatorial plane are formed. Solvent molecules such as water can be found in the crystal structure in the vicinity of thiocarbamide and selenourea ligands, which are oriented parallel to the equatorial plane. In the case when diphenylglyoxime is located in the equatorial plane, water can be found in the vicinity of parallel and perpendicularly oriented ligands. The molecules within the crystal are arranged so closely that there are no gaps in the crystal lattice of these compounds.Keywords: Co(III) dioximates, fl uorine containing anions, ligands orientation, H-bonds, biostimulation properties. IntroductionThe use of ligands containing oxime functionalities creates prerequisites for assembling of coordination compounds with diverse composition and architecture: monooxime ligands are widely used for clusters synthesis [1,2] and compounds with polymeric structure [2,3]; dioxime ligands are often used for the synthesis of mononuclear compounds [4]. However, due to their ability to coordinate both through the nitrogen and the oxygen atoms of the oxime group, it is possible to obtain heteronuclear complexes as well [5]; by combining IIB group metals with some dioxime molecules coordination polymers have been obtained [6]; polyoxime ligands are used for the synthesis of poly-and heteronuclear compounds [7].Transition metal compounds with chelate ligands have an important place in coordination chemistry. Dioximates of transition metals also belong to this class. The coordination ability of α-dioximes to d-metals have received considerable attention not only from the perspective of synthesis of B 12 vitamin models or hemoglobin [8], but as well as substances that feature a broad spectrum of synthetic, analytical and structural possibilities. Dioximes can be used as catalysts in industrial processes [9], stimulators of erythropoetic functions [10], antihypoxanth drugs [11], antidote properties [12], as basis for the obtaining of new semiconductors [13], for the separation and purifi cation of metal generating complexes, etc. It has been found that some dioximes play the role of a bridging ligand in the systems of iron complexes [14]. It should be mentioned that in this role, the dimethylglyoxime molecule has a trans confi guration, as in the free crystalline dimethylglyoxime.The diversity of transition metal dioximates is represented by the mono-and polynuclear, heteronuclear compounds with ...
