The reaction of (arene)RuCl2 (arene = cymene, 1,3,5-C6H3Me3) and Cp*RhCl2 half-sandwich complexes with tridentate heterocyclic ligands in the presence of base has been investigated. In all cases, the chloro-ligands were substituted to give metall ...
Upon reacting P4S3 with AgAl(hfip)4 and AgAl(pftb)4 [hfip = OC(H)(CF3)2; pftb = OC(CF3)3], the compds. Ag(P4S3)Al(hfip)4 (1) and Ag(P4S3)2+[Al(pftb)4]- (2) formed in CS2 or CS2/CH2Cl2 soln., resp. Compds. 1 and 2 were characterized by single-crystal x-ray ...
This thesis is concerned with supramolecular architectures assembled at metal surfaces. The investigations pursued two objectives. On the one hand, the focus was placed on the fabrication of low-dimensional surface-supported network structures by applying ...
Highly reactive tris-carbene Co(I) complexes [(TIMENaryl)Co]Cl react with org. azides to yield monomeric Co(III) imido complexes (TIMENaryl)Co(NAr') (aryl = mes, xyl; Ar = -C6H4-CH3, -C6H4-OCH3). The cobalt-imido fragment in these complexes is elec ...
Reaction of the dimer [(η5-C5Me5)RhCl(μ2-Cl)]2 with 2 or 4 equiv of the water-soluble phosphine 1,3,5-triaza-7-phosphatricyclo[3.3.1.1]decane (pta) affords [Rh(η5-C5Me< ...
The conformational analysis of a series of configurational isomers of 2-(hydroxymethyl)azepan-3,4,5,6-tetrols 1-4 has been carried out. H-1 NMR spectroscopic data, especially vicinal J couplings and nuclear Overhauser enhancements (NOE), assisted by molecu ...
In analogy to the authors' successful PX2+ insertion reactions, an AsX2+ insertion route was explored to obtain new arsenic halogen cations. Two new salts were prepd.: AsBr4+[Al(OR)4]-, starting from AsBr3, Br2 and Ag[Al(OR)4], and I2As-PI3+[Al(OR)]4 from ...
The synthesis of the potentially nonadentate ligand 1,4,7-tris[(6-carboxypyridin-2-yl)methyl]-1,4,7-triazacyclononane (H3tpatcn), a new derivative of 1,4,7-triazacyclononane N-functionalised with three pyridinecarboxylate arms, is described. The complexes ...
The synthesis and structural properties of three new hydridorhodium(III) complexes are reported. Hydrogenolysis of the cyclometalated Rh dichloride complexes [RhCl2{(S,S)-benbox(Me2)}] (2a-c; benbox(Me2) = 3,5-dimethyl-2,6-bis[(4-R1-4-R2-4,5-dihydrooxazol- ...
Clusters of metal atoms at a fixed size can assume different structural arrangements, known as isomers, which may have nearly the same energy. Therefore at given experimental conditions distribution of these isomers can be present. While the size selection ...
