“…10 However, it is distinguished from the previous complexes that one uncoordinated 4,4-bpy The cis-and trans-L-Mo-L angles are in the range of 76.45(5)-105.15 (7) o and 154.94(5)-169.83 (7) o , respectively. To a large extent these distortions stem from the incorporation of Mo into a five-membered ring.…”

Molybdenum chemistry has received the intense attention because of its relevance to the active sites of molybdoenzymes. The presence of the cis-dioxo-, in the oxidized forms of certain molybdoenzymes has stimulated both the search for new structures in which this moiety is coordinated to ligands containing nitrogen, oxygen and/or sulfur donors and also the study of their chemical, spectroscopic, electrochemical and structural properties. 1-5Tridentate ONS-chelating ligands derived from thiosemicarbazide or dithiocarbazate of salicylaldehyde have been widely used in much of this work. 6-9The tautomerism (Scheme 1) of these ligands as well as the well known tendency of sulfur donors to act as bridging ligands allows various structural possibilities for the corresponding metal complexes.As part of our studies on the coordination chemistry of d-block metal complexes with Schiff base ligands, we have earlier described the synthesis and spectroscopic and electrochemical properties for the molybdenum(VI) complexes, such as [MoO

“…Such compounds that have N, O and S donors are good metal-chelating agents [1]. In the last few years the structure of vanadium complexes is of particular interest because of their model character for biological function of vanadium [2].…”

Keywords: hydrogen bonding of coordination compounds, ferrocene compounds, homogeneous catalysisStrong intramolecular hydrogen bond was observed in various substituted ferrocene 1,1'-diamides pepared via homogeneous catalytic carbonylation starting from 1,1'-diiodoferrrocene. Structure of (N'-butyl-carbamoyl)-morfolino ferrocene carboxamide was determined: Existance of thione-thiol tautomeric forms is the structural characteristic of the thiosemicarbazones derived from salicylaldehyde with the thione form dominating in the solid state. In the structuraly characterized complexes vanadium was found in the tetragonal-pyramidal environment with the oxo group in the apical position and thiosemicarbazone acting as a tridentate ligand. A molecule of solvent completes the coordination sphere of vanadium.[1] Cindrić M.,

“…The complexes [MoO 2 L] n (1-3, described in here-presented study and 4-8, known from our previous investigation [17,18]) were also tested for their antiproliferative ability against selected human tumor cell lines and compared to parent thiosemicabazone ligands. Here presented synthetic, structural and biological studies have been carried out in order to obtain information on structure-activity relationships for systems involving molybdenum(VI) ions.…”
