Tetracarbonyl Chromium Complexes with Me2SbESbMe2 (E = O, S) and MeSb(SSbMe2)2 as Ligands Me2SbOSbMe2 reacts with nbdCr(CO)4 (nbd = norbornadiene) to form cyclo-[Me2SbOSbMe2Cr(CO)4]2 ( 1 ). The reaction of Me2SbSSbMe2 with nbdCr(CO)4 gives cis-[(Me2SbSSbMe2)2Cr(CO)4] ( 2 ), a complex stable only in solution. With excess nbdCr(CO)4 also cyclo[Me2SbSSbMe2Cr(CO)4]2 ( 3 ) and cyclo[MeSb(SSbMe2)2Cr(CO)4] ( 4 ) form in low yield. The crystal structures of 1 , 3 and 4 · nbdCr(CO)4 are reported. The novel ligand MeSb(SSbMe2)2 is formed by elimination of Me3Sb from Me2SbSSbMe2.  相似文献

Eight new antimony (III) complexes containing dithiocarbamate ligands (R2NCS2)2SbBr [R2NCS2 = OC4H8NCS2 (1), C2H5NC4H8NCS2 (2), Me2NCS2 (3), C4H8NCS2 (4)] and (R2NCS2)3Sb[R2NCS2 = C5H10NCS2 (5), Bz2NCS2 (6), Et2NCS2 (7), (HOCH2CH2)2NCS2 (8)] have been synthesized by the reactions of antimony (III) halides with dithiocarbamate ligands in 1:2 or 1:3 stoichiometries. All the complexes have been characterized by elemental analysis, melting point as well as spectral [IR and NMR (1H and 13C)] studies. The crystal structures of complexes 1, 5 and 8 have been determined by X-ray single crystal diffraction, and their electrochemical character has also been studied.  相似文献

Understanding the interactions of organic donor and acceptor molecules in binary associates is crucial for design and control of their functions. Herein, we carried out a theoretical study on the properties of charge transfer complexes of 1,3,6-trinitro-9,10-phenanthrenequinone (PQ) with 23 aromatic π-electron donors. Density functional theory (DFT) was employed to obtain geometries, frontier orbital energy levels and amounts of charge transfer in the ground and first excited states. For the most effective donors, namely, dibenzotetrathiafulvalene, pentacene, tetrathiafulvalene, 5,10-dimethylphenazine, and tetramethyl-p-phenylenediamine, the amount of charge transfer in the ground state was shown to be 0.134−0.240 e. Further, a novel charge transfer complex of PQ with anthracene was isolated in crystalline form and its molecular and crystal structure elucidated by single-crystal synchrotron X-ray diffraction.  相似文献

The concept of direct synthesis (the use of metals or their oxides as the starting materials for obtaining coordination compounds) has been further developed as anion-deficient and ligand-deficient methods for synthesis of heterometallic complexes. We have used the example of coordination compounds with amino alcohols and ethelenediamines to demonstrate the advantages of the proposed approach for obtaining polynuclear, mixed-anion, and mixed-valence heterometallic complexes. We present the most interesting crystal structures of the Cu–M (Co, Zn, Cd, Pb) hetero bimetallic complexes. It is shown that direct synthesis of hetero trimetallic complexes can be a further possible development of the new concept.  相似文献
